whats your dimension numbering scheme
I am refering to the dimension of space.
Space, the final frontier
@static loom dimension numbering schema 
tessaract is just a simulation of what it would be
schema? CSS? Front end web dev? count me out!
go read about json schemas
idk what they are but they sound horrifying
HELL.. NO!!
But you have a good understanding of what we know of the 4th dimension, yes?
hold up
@static loom does it exist tho
json does exist unfortunately š
i'm not sure we know whether a 4th spatial dimension exists
oh wait you're talking about the other thing
ok tbh json isn't that bad and maps on relatively nicely to python data types
yeah
@vagrant python
json has like
4 data types innit
string number boolean and moar json
oh and arrays
there isn't an irl 4th dimension
and undefined
chrew
there is a irl 2.5th dimension
for some reason hashmaps in js (and json) are called objects
sorry, i might have to leave soon
mathimatically, it does, right?
back to the 4th dimension?
like they don't even TRY to pretend objects aren't hashmaps with an ego
python objects are pretty much fancy hashmaps
and lua tables are combined hashmaps + arrays
not in real life as far as we know
yeah
and other langs too
but like
c'mon at least TRY
the c++ compiler uses hashmaps for them i bet
javascript objects sort of have extra stuff
i forget what they're called, but it's similar to lua
they both do prototype based OOP
alright
i am back btw
that makes sence
Why is it?
Peace out
War in
In today's teaching assistant training, I learned that the sandwich method of giving feedback is outdated. Which is crazy since I learned it only a few years ago.
The new method starts pretty similar, but instead of the last "bun" we have "next steps to take".
"Strengths" -> idk i forgot -> "next steps to take"
clearly if they used the bun method you would have remembered the middle step 
tbh you have a point there. The bun/sandwich method is easy to remember. Anyways I wrote it down in a post-it so hopefully I can find it for the next time I need to use it.
Until I find it, anyone that asks for my feedback will get lots of praise, followed by what next steps they should take 
ah I should've posted this in math pedagogy mb
how do you stop hating yourself for not figuring things out independently and how do you stop loving yourself for figuring things out indepedently
You dont
No further comments
yeah pushes you down the nihilistic well
Man
This isnt completely black and white for me
My brain has subconsciously created boundaries for me to be comfortable but it did forget to make it inaccessible
I think its important to recognize why you have these problems of why you cannot figure it out independently perhaps
I have a habit of questioning every step along the way because your proof should also convince you too
yeah right, thats exactly what improvement is essentially
i mean i am ok with what transpired in this case
i could see the thing coming but not in its full glory
and thats by nature
No clue what that means but sure thing
Its like i had an intuition that things would fall in a certain way it is just that it wasnt as exact as the formalised form
and thats just down to the work i put in
to get it filtered perfectly
So I guess the important thing especially when trying to get this intuition right is also being able to admit that maybe you did something wrong and search up the solution after your attempt anyway; that is one way
i just want me to be communicatively unambiguous enough
I personally think being able to relay communication clearly and concisely of a proof comes with time or you can also read a philosophical logic book
right
What year are you?
No
Oh?
Well just try to have fun then, no need to cram it all in one go
If its hard, take some time away and try again later
I thought this was for a class
its just the competitive genes taking over i guess, cant help it sometimes yknow
who are you competing with tho lol, like it shouldnt be a competition to begin with just go at your own pace and have fun with math otherwise whats the point
my massive copium meter is going bonkers
its important to take a step back and just have fun with the content otherwise you will never put the effort into understanding and learning and actually applying/remembering the content you just did
like if i did cram everything i learned, oh god i would never know how to apply to other areas
i dont think its cramming
like i can think very clearly
but only very narrowly at any given time
its like mood swings
my latest obsession is how are the defintions making sure what we are studying is exhaustive
i hate myself for this
it just blurs my vision all the time and stops me from being more creative
like are you questioning the conciseness and quality of definitions?
yes
maybe this is gotta do with the content im playing with but yeah im also overlooking some details i dont expect my ass to overlook
I dont think you will get far by doing that because if anything just read the papers associated with it lol and maybe if you can understand that, then you can question whether or not it is truly exhaustive. It usually a waste of time, but its more example to look at examples associated with the definition rather than the quality
well waste of time is subjective isnt it
Yeah thats true
Something to consider is that with every definition and theorem, you should be able to recite it and also give an example of suck
If you can do that, that is generally a good direction to move forward
There is not a huge need to look into the background of subjects until you gotten to a point of mastery to being able to question such
its like i do what i do in this field because i love doing it and truly dont care if it follows a certain type of adjective unless im able to perform a body of work that grabs adjectives more dynamically
Yeah correct
Ability to ask questions
and their quality
ok i should reframe my original question
how do i make myself THINK of questions independent of my state of mind
this is starting to sound like how do you enjoy music youre not in the mood of listening to but it is also something that youd love to have only if you were in a different mood
is this sentiment something that arises due to not being totally bought in into the idea of the subject youre studying (like i need to focus harder or something like that)
yo
hi
Intelligent design creationism (often intelligent design, ID, or IDC) is a pseudoscience that maintains that certain aspects of the physical world, and more specifically life, superficially look designed, and hence were designed, by an intelligent being (usually, but not always, the God of the Christian religion). Although the concept is pre-sci...
in short there's no proof that God exists
you can't use the scientific method to test if a God exists or not
yeah but like
what about the proof i just sID
comparing "finding a spaceship in a forest" to our formation is a far stretch
so like it's impossible to debunk that God doesn't exist
we were made from evolution
How does that argument hold any weight when you canāt determine what the space of outcomes is to begin with
you could point to anything and say that's proof
I'm talking about what you said, yes
CAN a space ship be made with evolution
babel fish argument moment
..
yes
now you don't understand evolution
or the scientific method great
you're just damn uneducated
bro,convinse me
Who created god blows this argument out of the water
why should I have to convince you evolution is real
fax
@heavy sinew
if u say god exists
when it's been an accepted scientific theory for hundreds of years
then who made god
If we had to be intelligently designed how can something capable of intelligently designing us be natural
and you can search everything you don't know on Google
Unless youāre just like being hypocritical with the reasoning
Which is usually the case
i personally am atheist but if someone shows me a convincing peer reviewed study saying that god exists then sure
god is out of logic, trying to undrestand who made it,how it look... is like a cat trying to undrestabd quantum phisics
I mean yeah like Iām not gonna claim itās possible to prove god doesnāt exist but Iām also not gonna claim that itās possible to prove I wonāt die from the next sip of water I take
Like this is a question of empirics
yeah so it's impossible to know where God comes from, I agree
we are juste unable to prove it becuse we are dumb
so basically ur answer is you dont know?
very dumb
yes
but u just said ur gonna prove god exists
i poved that he exit
āI donāt know therefore itās trueā
what? spaceship?
I personally believe actually that the God in the heavens is a really evolved human
u asked who created it and i said i dont knoe
someone who has lived through millions of lifetimes if not billions
yeah this is legit
legit belief
and ascended to a world beyond Earth
that is what some sects of Christianity and other religions believe
that's what you missed,he is not mesured with time
he didnt made up at some point
and hewill not end
Damn, that sounds⦠unlikelyā¦
and now this is a religious argument yay
yeah i also like to believe god is from like a type 6 or 7 civilization
he made time
Frfr
~~the sheer disrespect to push up my convo for this shiet~
but then you're using faith or imagination to conclude that
no bro he is out what anyone can even imagine
what you say cannot be concluded by with reason or logic alone
you're imagining him right now
that's logic
jesus
Can you help me with something
what
Check DMs
@heavy sinew do u have any other proofs for why god exists apart from the spaceship in forest example
that was a very strong one so i didnt search more
because it seem theonly response
of what i said
Now I know why they find it necessary to teach people modus ponens
convinsed?
and you south?
i'm atheist and i haven't been smited out of the skye yet so god might just not care tbh
leme shearch for you
LMAO I was just about to suggest the skye thing
ultimate sniped
maybe god laws only apply to those who believe in him i guess
or else every religion's god would start bullying us
lol
do you thing univers has been made by it selfe?
what is wifi receiver
thatās me
To ask for mathematics help on this server, please open your own help channel or help thread. See #āhow-to-get-help for instructions.
I mean you think god has been made by himself
its phisicly impossible
yea probably, cuz of quantum fluctuations
How is god making himself physically possible
is there a cyberhole where i can store all my wifi signals?
you mentioned quantum mechanics - so u would know that its possible right
you have to be 13 years old or older to use discord
he's 20 btw
well not everyone acts their age but....
hey hes 20
that's why I had to ask
no bro ,only in this conversations i cleard that 3 times,god didnt made up,time doesent apply on him,he mde time.he just existed and exist and will exist
yeah and iām benedict cumberpatch
i am acting old or young?
old
bro,tnx
Bro why is there this like fundamental disconnect whenever people argue this
like they say ādo you think we came out of nowhere bro? LOLā and then the next word out of their mouth is that god needs no creator
btw i am 19(close to 20)
wow thats nice. you know all this at 19
Fuck thatās pretty convincing man
@heavy sinew bro its just wasted conversation we have freedom to choose which religion we follow but we have must become human its matter not this religion or that
youre acting
@heavy sinew so u were saying that humans coming into existence as a coincidence is dumb. but ur kind of saying god also came into existence as a coincidence
tnx bro , that's because it doesent sound logic to sya od exist with proff so i searched about argumments and coarguments...
see
i am eternal
Fix my cpu
do you thing univers has been made by it selfe?
its phisicly impossible
I mean you think god has been made by himself
no bro ,god didnt made up,time doesent apply on him,he mde time.he just existed and exist and will exist
btw you might be interested in reading this
explaining how God might be a thing of human society, when we worshipped chiefs and people more powerful than us
oh itās discussion 2
i said 4 time now in this conversations he didnt made up,he is out time .he made time!
oh woops I had this other one in mind
both are good reading I believe
what ur saying doesnt make sense. what exactly do u mean he is out of time? where is he? 4th dimension? sorry im not understanding
bro that look boring,say what it has briefly pls
this chat is way more fun than discussion tbh
Heaven and hell are subspaces
literally just told you
just that I can't prove that God being an eternal timeless being is wrong
you also can't prove me wrong
no not 4 th dimention, and you cant undrestand,i also dont undrestand,because we are dumb.trying to undrestand how somthing out time is like a cat trying to undrestad philosophy class.in islam god told us literally to not thing about this too mutch because we will not undrestand
we're talking about something that is impossible for our puny human minds to understand, after all
wait till i read what you said
saitama
youre trying to undrestand somthing that out of logic and time
you simply cant
you said earlier that you know God exists using logic
I asked if you instead meant that God exists through faith and imagination
you said no
What is a proof
.
i proved it earlier
@heavy sinew what if i say theres a heavenly cat sitting at the centre of our earth controlling the whole universe
i mean we cant prove it doesnt exist yet
so maybe its real?
its out of our comprehension so
okay so no human being can understand God cause we're all dumb
maybe
but somehow you can?
Hello discussion 2
God is maths simple as that
can only prove that he exist
hello hollyhock
thanks for what you said
but in the middle of ur proof u jsut say we are all too dumb and thats the end of it
Based anti constructivist
wait were still talking about this š
its better than watching anime
its been like 15 minutes, i literally had a whole convo with someone irl
yeah that's the point
i dont see Mike Tyson smacking the hell out of Jake Paul in here
Trying to prove the existence is god is like me saying there was something before the big bang. Is it possible? Yes, is it's also not possible. Yes? So it's not really worth arguing over
sounds a lot like faith and imagination to me..........
Of*
i am like mike tyson in the sense that iām washed
if you can't use reason cause no human being can describe God
what did you said earlier? as a coargument?
I'm not attacking faith and imagination btw
that was something different. my argument is above, scroll up
those are perfectly fine ways of understanding the world
yeah thanks
my point is that you can't use reason alone to 'prove' God exists
you need some other methods of thinking about the world
like culture
which is subjective of course
Also if god is real he very clearly made this universe the way it is and gave us maths and science as a key into the heavens as u might put it
homander
afterall we cant prove most things for sure. we can only hypothesise and observe
anthropologists do this for a living and I respect them
but in this case we cant observe
exactly
bro i literraly proved it using the space ship
we can't use empiricism
We literally have maths problems that are to hard to solve right now I think that's sorta proof enough that you can't really get closer to god then maths
yes
that's a major part of reason excluded
teleological argument is not "proof" per se
also I've studied some philosophy
scroll up pls
yoo can we be friends
okey wait lil bro
whenever i talk about philosophy ppl tell me to shut up
Both are important, both can be equally unwelcome to talk about. It's about time and place.
that?
I've found alot of high level physicists sorta develop into agnostic philosophers
no, hold on
there's also like rationalism but you know.....
That's very true yes
this
pls clear my doubt
bro are you convinsed
now?
you're anti-convincing me
Maths can't explain god but maybe one day it can fill in all the gaps around the idea of god thus giving us the outline
Respectfully, @heavy sinew, you really shouldn't expect to convince people about fundamental tenets of your belief system through a 15 min discord conversation
nah, humans wont last that long
Yeah
besides we cant fit that much into our brains
Plus I still like to believe that after death there's something more then this in a universal and scientific sense
hmmm
The quantum is just to confusing for me not to question
maybe u just respawn with ur memories erased
that's a good one
theres infinite possibilities
Or maybe it's just a repeat
that too. its depressing
that could explain deja vu
Like the universe expands and matter sorta morphs back into this singularity state causing the infinite to be refilled
idk man you got me here
i'l search and gve you a response
God isn't really less depressing
after some 20min
Look at our current state of the world and then think about a god that can actually see what's going on
ok
Ether there's a larger reason or he kinda suxks
Idk I like talking about these things the same way doing non ending calculations is interesting
why?
Because just maybe one day something will click and you'll realize nobody came to that conclusion
off topic but how did you get through Bojack without getting terminally depressed
whats bojack
Jokes on you I was already terminally depressed!
wdym? Bojack is pretty fking good
Bojack Horseman, it's a tv show that her pfp is from
yeah it's also pretty fking depressing lol (but I'm only on s2 or 3(
I like that banner
h
ok sorry I didn't mean to derail
Also I'm amazed that mathematics will dismiss the idea of god then emeditly talk about something like the Collatz conjecture
Mathematicians*
To many fucking letters

publishing my proof of god to vixra ā¤ļø
I'm curious how these are connected in your mind
Like the fact basically every number comes back to that repeating the same 3 pattern and we just don't know why or what or how
Or what even are prime numbers
Why do they exist
mathematicians donāt just assume that that happens
Well we donāt know if this is true
well we prove it from axioms
no we donāt
Ring theory
that's nothing compared to infinity, you should understand that :)
Do you think a 20 min conversation held primarily in incomplete thoughts and sentences over a message board that rapidly moves from topic to topic would be enough to convince you of atheism? Polytheism? Deism?
You seem to view your beliefs as so self-evident that a 4-sentence, loosely worded example is enough to convince other people of their truth, but it really isn't. Everyone else here holds a unique set of beliefs born from their upbringing, life experiences, and their own thought on the matter. To change that is not a trivial undertaking, and quite frankly it seems arrogant to assume that it would be.
30 to the 10 or something
Well I think that cones back to infinity
In the way some infinites are smaller
Like our universe expanding implies a something else
But also we don't really have any way to find that out
Was maths invented or discovered
@coarse bridge I'm gonna send this to bf to annoy the shit out of him
Did we discover food
i am not trying to convinse them(i m sure even if i was right they wont accept it) but trying to know their proofs and arguments ,and their point of vue.got it?
Why would that be a annoying statement
I would argue primarily invented as a model to explain our world
Keyword: Collatz
Is the 2 + 2 = 5 prof actually Legit or just gimmickry
LMAO
One thing maths explained everyone that they will die virgin
usually gimmicky or an exercise in spotting errors, unless those symbols mean something unusual
like south,i am sure he didnt see anything wrong in my proofs so he didnt respond(i would do the same)
Is he not a respected mathematician?
got it LG?
the cc is notorious for amateur mathematicians attempting to prove it bc it's so simple and "obviously true"
Except you keep framing it as "they won't accept my argument" and not "which part of my argument is unconvincing".
And I wouldn't be so convinced that no one sees anything wrong with your "proof". I imagine one could find several responses under the category "rebuttals of the teleological argument".
Which makes it even more interesting
Because it proves that it's to complicated for current mathematics
Like we can't solve it right now
until you get the fifth obviously wrong proof posted in #discussion in a day
Oh I mean yeah that's obviously extremely annoying
Like I sorta mean today the thing that made me join this discord a couple hours ago
Any male mathematician who slays ?
ebuttals of the teleological argument i didnt undrestand this sentesne(i am not english speaker)
pls explan

The spaceship example you gave is an example of an argument for the existence of God called the teleological argument, (generally) arguing from the perceived complexity of the universe to the existence of God. This argument is quite old, and plenty of people have argued against it, for various reasons.
Here is the SEP page discussing some versions of the argument along with some objections: https://plato.stanford.edu/entries/teleological-arguments/
ok bro,tnx
yo saitama If the first cause is necessary and eternal, it cannot be a contingent being (i.e., a being that depends on something else for its existence). Thus, this first cause must be unique (because there can only be one uncaused cause), and it must be all-powerful and timeless, which fits the description of God.
i cant read that! its too tall
Be careful not to mix your Aquinas with your Hume š
The wording you used in the response is very reminiscent of a medieval Catholic philosopher named Thomas Aquinas
i dont know that
i am muslim
not catholiq
oe idk
are you religious or no by the way
fair enough, but Aquinas had what he called the "5 ways" which he believed to be proofs for the existence of God
The language the above comment was worded in seemed very Aquinas-like
very much not
why
yeah
i didnt know there is a lot of not religious people btw
Well, the argument you have given, while it may be yours in its realization, is not new in its form
Again, it really falls under a broader class of teleological arguments
There are a lot of answers to that question: some are small, some are big, and I'm not really interested in listing them here
so why are you trying to prrof them wrong then
and are you not religious because of your family or because you decided to
bruh
The only thing I am trying to do here is to point out that the "proof" you have given a) is not a new concept to this debate (in the general sense) and b) is not a proof
Again, it really isn't
š¦ šæ
you cant just say it isnt a proof
and pls dont send me some tall report or smth
and dont ay complex words as what you said earlier
and dont tell me some historical events or smth
go strict to what you want to say pls

because if you do that you will juste mess everything and i will forget what are talking about
remember you are proving that my argument is false
let him type š
Not really, all I am aiming to show is that your argument is not necessarily true ...
yaaaaaaaaapper
ok bro
are you old enough to be here
i am 50 is that enouph?

But I understand

@zinc glen
pls type somthing short
shut up woman
i am a man thank you
shut up man
hhhh okey

bro what are you typing there are you seriously trying to prove that i am wrong?
he's tryna prove that your argument is logically invalid i think
remember this comment:
nah
bro can someone teach me logarithm in deep or can provide some video or resource
he will start typing some complex words and historical events and talk about philosofy,but at the end he will not prove anything
khan academy
that's the religion room go to discussion to know that
@unborn meteor mark my words i will need you to witness
ok
nah
why?
bye
No, more like the argument doesn't actually prove anything meaningful
are you seriously treating a complex and nuanced reply as a bad thing?
saying somthing complex and doesent get to the point.isnt that bad
can you explain what is cranks?
Bro tried to slip in the "doesn't get to the point"
im sure theyll be making a point
Sometimes a mirror is more useful than a dictionary
i really dont know what it mean
you would much rather be epicly owned by a small, funny quip thatās extremely difficult to reply to because it lacks any substance!
bruh
so i dont know you and you dont know me and you shosed to say somthing bad about me huh
well, i donāt know you so i canāt say anything bad about you
i am just giving you a funny response
bro
it was objectively hilarious
bruh
ok sir
i am just gonna ignore you
listen iāll be here all week. i work for tips! put āem in the jar!
ignoring a mod great idea
okay iāll stop antagonizing you now
but for the record i was objectively, indisputably funny, as always
I'll agree with that if you help me in math discussion
sorry i canāt because i am gonna get to therapy, but since it was indisputable you canāt dispute it and be right anyways.
good luck with ur problem
š
what do you need lil man
Check #math-discussion
Fine, since you are so intent that I "strictly" counter your argument, lets condense this into a rough syllogism:
A) The probability that you find a space-ship in a forest is exceedingly low.
B) The probability that the body occurs "coincidentally" is comparable to that of finding a space-ship in the forest.
C) We should not accept the truth of a proposition if the probability of it occurring (on our premises) is exceedingly low.
D) By A, B, C, we should not accept the proposition that humans (or bodies) occured coincidentally.
This is not exact, but the initial argument wasn't really exact either so š¤·āāļø
Objection to B: this is essentially one of Hume's objections to the teleological argument as well. Not only do we not have any reason to accept this premise a priori, the analogy between the two situations described is not very good. Nature, and the things living in it (including our bodies), are not like nonhuman artifacts, and there are substantial differences: living vs. nonliving, self-sustaining vs not, etc.
Objection to C: This is a tad more subtle, but this should be replaced by: We may accept a proposition (even one with exceedingly low probability) when we have reason to not believe an alternative explanation or (as is more fitting in this case) we have no substantial reason to believe in the alternative explanation.
Related objection (though not an objection directly to the argument): Even if we accept this argument in its entirety, this does not get us to any sort of theistic god. The most this argument gets us to is an "order principle" which is capable of causing complexity.
Again, this is a rough rebuttal to a roughly translated syllogism, so if you are any way actually interested in responses to the argument, you really should check out the SEP article, or at least look for responses to the teleological argument.
and no, you don't get to ask for "strict" disproof and "short" in the same breath
objection to b: you are saying that nature is not like nonhuman artifacts so the analogie arent correct right?no ,because actualy both of them are made by ressource that exist i the universe ,if we assumed that you are correct.then in an environnement that full of iron and matterial necessairly enouph to make a ship it is normal to find a ship.whish it wrong.its like saying that we putted all the matterials neddet to a ship to be made and putted energy the ship will be made wish it not true
that's my reply on b
wait till i read c
Objection to this objection: There are known, evidently substantiated processes by which life becomes more complex in the presence of appropriate material (organic chemicals, etc). There are no known natural processes by which the material elements of a space ship may permute themselves into a spaceship.
"more compkex" yes but not made
it is real that life may get complex by biologie(wich it also made by god who made every phisical law) but can be made
That's not really true either: https://www.ncbi.nlm.nih.gov/books/NBK26876/
To fully understand the processes occurring in present-day living cells, we need to consider how they arose in evolution. The most fundamental of all such problems is the expression of hereditary information, which today requires extraordinarily complex machinery and proceeds from DNA to protein through an RNA intermediate. How did this machiner...
You don't need to know that
Old enough to be a Ph.D. student, that's enough info
yes that's enouph
You're in no place to say "bruh" my guy
did you skip the part where evidence disproving what you said was given
you can't explicitly lie about your age and then expect other people to report their age willy nilly š
i cant argue with a phd student and another guy sorry
skill issue?
yes i don even study phillosophy,he look like he studied it
Maybe that's an indication of something
i am like arguing with the main boss
Any philosophy I know is entirely amateur; I do math primarily
Anyway, I'm no longer interested in this discussion. If you are actually interested in the actual scholarly debate on the teleological argument, here is the SEP article again: https://plato.stanford.edu/entries/teleological-arguments/
Idk if they have translations if that is an issue, but there are certainly more sources included here.

What is e^ln0
How to understand the inverse function is g(f(x)) = x, it is quite clumsy and mixed. Can someone explain and prove it?
This is just a definition, there isnāt much to say. A function g is said to be the inverse of a function f if for all x in the domain the composition g(f(x))=x
The idea is that g is just undoing whatever f does and gives you the original input back out
So how to prove it and understand from y=f(x) and turns into inverse?
if you struggle with that, think in some example:
if your f(x) := x + 5 and g(x) := x - 5
If you do f(g(5)) = 5, the idea is that if you do g(5) you get 0 and if you do f(0) you get back to 5 (the initial value).
They are inverse...
Also, that's the definition, there's no proof needed as mentioned above
hi, for math help, you should probablyā¦
a) open a help channel (see #āhow-to-get-help) or ask in the appropriate subject channel, and
b) just ask! you donāt need to ask if anybody is able to help you 
I already did
And
No one is answering
Also
Thereās people who submitted their problem after me
Who got an answer
in that case, just be patient! the helpers are all volunteers, and help is not guaranteed
sometimes it can take a bit
Can you help me?
Iām unfortunately not able to at the moment, apologies!!
Ok no problem
good luck with your problem, and have a good day! 
strictly speaking it's not defined
there are obvious ways to force it to be defined in which case it must be 0
How to know the function is one-to-one? And why?
This is going to depend, a common way is to assume that f(x)=f(y) and show that you must have x=y
Check if it is both injective and surjective
Aka bijective
Aka you can invert the function
One to one is injective
Oh
Bijective is one to one and onto
Oh I see
I always thought one to one was bijective lol
Mb
Well to show if a function is injective you have to prove
f(a) = f(b) => a = b
If youāre dealing with say linear maps between vector spaces however itās a fact that the function is injective if its kernel is trivial, so in that case you have another way to approach it, and this is often easier
for all a and b in the domain
Yo does anyone know if this is legit https://www.non-trivial.org/
I'm in hs and getting an opportunity to do research in math would genuinely be my dream but it seems way too good to be true
Or do these things only take absolute geniuses and most people don't get in?
I searched about it on reddit and it seems "legit" in that they do select people and have them help on some kind of research for a few weeks, but the process is selective and involves a lot of phases, and apparently they have a system of referral codes which strikes me as really weird. It's probably some weird grift by Ivy alumni tbh
I also wouldn't do a program like this if you expect to do research in "pure math"
Ah, ic. Thanks for giving me a heads-up.
Do you have any other recommendations to places I could look if I was interested in doing research in pure math then? (This isn't just for college apps, I'm seriously considering studying mathematics in the future and I want to see what the research process was like)
since I'm not in the US other people will probably know better
Is that just for the Boston area?
this is one of the weird math terminology things, "one-to-one correspondence" means bijective but "one-to-one" as in "one-to-one function" or "one-to-one mapping" means injective
part of the reason why it's just easier to use in-/sur-/bijective
Ohh yeah I remember hearing it with "correspondence"
Yeah I always use the jectives
That's so weird though
It is slightly easier to work out which is which from the onto/ one to one names but itās just so much more ambiguous, Iām definitely more of an in/surjective kinda guy
onto is a weird af name
It kinda makes sense, I can see where it came from but I donāt love it
although surjective is just onto but french
injective and bijective actually seem intuitive
I will no longer be using the injective surjecrive terminology, thank you for bringing this to my attention

Dude I'm so smart I thought of a meme

"this is an on-function, an in-function, and a two-function"

hello, suppose a function approaching infinity was always fā > 0 and fāā < 0, would this indicate a sort of asymptote(theoretically)
not necessarily, just consider something like f(x)=log(x) which is increasing and concave
thanks, thats sort of what i had in mind i guess i misunderstood the meaning of asymptote
yeah I suppose f'' < 0 suggests that the derivative f' is decreasing with x, but you don't know how fast it is decreasing so you can't guarantee much regarding asymptotic behavior
again this isn't always true, consider something like f'(x)=1/log(x) (so f(x) could be just the integral of this function, e.g. from 1 to x). Then f'(x) is positive and f''(x) is negative for large enough x
in this particular example it is true that f'(x)=1/x has an asymptote
but it doesn't hold in general
@limber thunder how're you doing>

yeah sorry about that
kinda mid tbh but such is life
It'll get better, I believe
I need you to help me verify a proof
will you be able to do that
ah
hi
hi
can you help me in verifying an inequality proof?
i personally cant, but im sure if you post this in a help channel you should be able to get it verified
apolgies, im not the smartest person, and im even worse at teaching
you're blessed
Is there also help with ecology here or only math?
this is a math server.
there's a bio server

Who invented math?
aliens
hey guys, some time ago on this server i noticed there was a reccomendation to refrain from using chatgpt for math. Is that still the case? Can i rely on it to explain me theories or derviations of formulas for example?
Very much still the case
Itās just a consequence of how LLMs work, maths is logical and takes problem solving, LLMs just guess what the next word in a sentence is likely to be, and will happily make shit up when it has to
I understand that but doesnt that just make it bad for whenever youre trying to solve something? what if im just trying to learn theories and the intuition behind them, can i really not rely on it?
The o1 preview model is somewhat decent.
the less formal your questions are, the better it can perform
though in general i would be wary of getting intuition from elsewhere
intuition should be formed from working with the objects (which is necessarily done in a formal way)
sorry, i dont follow
you learn math by doing math 
and chatgpt is very bad at that
for getting an overview of some topic its fine, but you need to be critical with it
or just things like getting ressources
That's basically what I've been doing. In my case I have a lot of experience grading, so I can smell its b.s. a mile away.
good to hear, thanks for the responses
What do you guys do if YouTube videos can't explain/help you at a problem?
- what topic is this on?
- why aren't the YT videos helping in your case?
help me with English

- sin, cos, tan in a unit circle and parables
- It's only showing the basics and not specific types of problems that will be on the exam
if you want to practice harder questions then look in your textbook
yeah YouTube doesn't have that many good worked examples
it's only if you need help understanding what the concept is, I feel
the thing is I'm absolute shit at math and textbooks won't help me either
I'm searching for solutions based on the problems from the textbook
maybe you just need a different textbook
but honestly I feel the real issue is that learning takes effort
if you can't solve a problem when you change only the numbers in the question, you need more practice
also yeah getting an exposure to different problem types
also I'm not sure exactly what you mean by this
what I will say is that don't memorise problems word-for-word
learn techniques and steps you can use to attack a question
I'm ready to take the effort but I just can't get into it
maybe keep asking in the help channels
until you get the hang of the questions
Hi, I would like some help please.
Is there any calculations or something similar to find my possible profits on bitcoin?
I would like to know how much I would of made at the current price if I invested £50 in it last November.
Thanks.
you can't predict the madness of people
wait how much did your 50 pounds turn into right now?
you're asking for the percentage profit or loss right
there's an easy formula for that
I want to know how much a £50 investment at last November's prices would be worth now at the current prices.
But I am not sure how to do that.
did you check this yet then?
I did not purchase any - simply wondering
ah if your 50 pounds turned into 70 pounds
then your percentage profit would be (new - old)/old * 100%
or (70 - 50)/50 * 100%
,calc (70 - 50)/50 * 100
Result:
40
So you are saying £50 of bitcoin last november is now worth £70 at these high prices?
no
That is what I want to know.
you can perform the same calculation by replacing 70 with the current price
okay one year ago Bitcoin was trading at around 55,000 in my currency
it's at 148,000 now
apply the same thing
,calc (148000)/(55000) * 50
I've replaced 100% with your 50 pounds
Result:
134.54545454545
Result:
84.545454545455
this would be your profit
okay I see what you mean now
Bitcoin prices:
21st Nov 2023 - £28,531.34
21st Nov 2024 - £71,336.94
I want to know how much £50 would be worth today, if it was invested in Nov 2023.
sorry it does matter what currency you use, cause different currencies have different exchange rates to BTC
for the prices
,calc 71336.94/28531.34 * 50
Result:
125.01505362174
,calc 71336.94/28531.34 * 50
Result:
125.01505362174
So you are saying that my £50 from Nov 2023 would be worth £125 Nov 2024?
yep
Thank you
Lower than I thoought aha
I thought it would be a few hundred around 500 since it jumped nearly 40k
the more you invest the more you can win
the more you can lose also
that's why you might want to look into options trading for Bitcoin
Will do , thanks

this is excellent watching
also disclaimer, I'm not responsible for any decisions or financial losses
I am not a qualified financial advisor lol
Wasn't gonna hold you to them...
yeah just saying this to be clear
the options part comes in around 5:30 in the video
you can bet a smaller amount to gain the same profit as with a larger amount
but then you might also lose 100% of that smaller amount
uh oh weāre talking about options
uh-oh?

How to integrate tan^(-1)x?
[\int\arctan(x)dx=x\arctan(x)-\frac12\log(x^2+1)]

Compute using integration by parts
And the fact that [\frac{d}{dx}\arctan(x)=\frac{1}{x^2+1}]

It would work differently on different subjects
@alpine kindle
That's my humble opinion
Now usually it might work one way, but not always
the dunning kruger effect is not about what percentage of a subject you think you know
Yes but that depends on what part you know
not specifically anyway
I can have a lecture that opens a billion questions on a topic, or a lecture that opens none
this is the graph from the study
Yes
And what's usually shares is the difference exaggerated and wobbled
Alongside the assumed connection to the origin
Anyways my point still stands
It depends on the topic and how you're introduced to it
That's what I think
this is in psychology
But I might be wrong
It is
like
But if you subtracted the perceived from the actual
as far as i know
why would you connect it to 0
It would look like this if you connected it to 0

No
It's when you read it right and add your own assumption
there isn't a real gap

Which is worse
the gap is a percentile thing
Oh sorry

How to prove sin^(-1)x + cos^(-1)x = pi/2, if 0 <= x <= 1?
Probably use the fact that sin(x)=cos(pi/2-x)
Should I use the derivative for the inverse function to calculate x?
Does anyone here think that the way algebra 1 is taught in uni is too secluded and is not well motivated?
Without going to your uni and knowing whatās in algebra 1 and how itās taught this is impossible to answer
@hexed bronze I know I was a bit harsh but I wanted to give you a wakeup call, to be honest where other people in your life might have pretended everything was fine
I was more angry at the system that failed you, like your high school not teaching basic stuff, than you personally
especially since your profile says you're doing biomedical engineering
you need a solid grounding in the three sciences and later on, different branches of engineering physics and medicine
for such a STEM-intensive course you really need to speak to an academic advisor at your uni
either you are going to commit hard if you really want this degree and these careers
or you should consider switching degrees
in particular, it's easier to ask for help now when there's still enough time to change things around
than for you to fail or have to accept whatever consequences later on
Thank you bro ā„ļø
i will try
that's good to know
also from my own life experience, the best teachers in my life had high expectations cause they wanted us to do well in life
they never or rarely shouted at us or lost their temper
and they also never stopped believing no matter how hard the obstacles we faced were
I hope someone like that enters your life
good luck and all the best with your studies, career, and life!
I entered the best uni in my whole country and with the highest gpa engineering field.. if i did that with shitty highschool teaching i can definitely do the next 5 years of college šŖ
but yeah I've had times where these teachers would make me realise what I was doing wrong academically and it's definitely a hard pill to swallow
wow
congrats I guess
Yeah just a bit embarrassing my little sister in highschool knows more maths than i do
but it is what it is
its the byproduct of school cramming
ah I see, that seems counterintuitive, haha
but it makes perfect sense, cause if you were only asked to retain this knowledge until the exam
I crammed everything at the end of the year and got a good gpa otherwise im an idiot that doesnt deserve this field
then yeah that's unfortunate cause STEM really does build on previous knowledge
if you don't want that the humanities don't really have that structure
anyway not saying that you should switch

holy shit ive been doing math shit for 3 hours š¦
Well of course by algebra 1, I mean Modern Abstract Algebra. And when I say that if someone has any concerns about how it's taught I mean the general curriculum of teaching it through a bunch of definitions about groups, rings, fields and then see how they apply. I feel like the definitions are poorly motivated and that these could be taught in a better way
It could depend on how the instructor teaches it. So I'm curious the way you learned it, you're most welcome to share
This is not a feet server


send proof
I find it interesting no two of the regular people I see in the server share the same username. And moreover, most usernames are pairwise quite distinct. This is in contrast with me going to school with 3 people that shared one of my names as a kid.
I can guess some of the reasons behind this, but I still find it interesting.
Imagine you would have to use regular names as online monikers
Even in the AT server where folks are encouraged to use their names, there's very few repeated names.
People would use fake names, like "John Titor".
Hououin Kyouma
thats like the guy that claimed to be from the future
or some shit like that
fucking stein's gate brainrot
The main John Titor poster started posting on a forum called "Time Travel Institute" in November 2000. He used a nickname like "timetrave_0". He only started using "John Titor" when he started posting on Art Bell's Post2Post forum which required a binary name of that format.
ai companies made a bad move by managing to first automate a career where the people inside it are so insane they think life is meaningless if you don't do the stuff in their job
yeah
@cinder zephyr did you receive the message we requested to be relayed to you yesterday?
we had to make our gitlab private yesterday to rid someone very harmful to us from following our profile, that also removed you as a follower, so we wanted to let you know you'd need to re-follow our profile to get code update notifs and stuff
I follow your gitlab?
you were
oh ok
i am so fucking sick of seeing this immature ass worldview on ai art, that somehow generative ai has not only removed any fun you can have by creating art but also that you're doing some kind of pro-human anti-capitalist jihad by not acknowledging that ai can make good art
I think the problem with it isn't that AI can't make good art, but the sourcing of the material used to train the generative models.
there have been a fuckton of jobs that got automated the past, idk, 20 years? and this is the first time I see anyone going "life is meaningless now" cause the ai is threatening their jobs, like more power to these people for enjoying their job so much but also you have to be mature enough to acknowledge that maybe there are other meaningful activities in this world?
it is interesting to see gitlab get some use
Iāve mostly only seen it cuz GNOME hosts their source code on there
always good to have an alternative to github
fuck microsoft
my internship used gitlab but we switched to github cause it was cheaper after a number of people i think.
i distrust this argument. it reeks of... after-the-fact?
like why did i not see this argument being tossed around when models were smaller? there were models being trained on copyrighted data long before chatgpt, and i didn't see anyone pointing their fingers and going "ooh that's stealing!!". it only became an "ethical concern" after it turned out that the ai might take your job.
there's also the usual argument that humans take inspiration from human art in the same way that ai do, and there isn't something fundamentally better about how humans do this, yada yada yada.
but there is also another less usual argument i want to put forward. nobody on the face of this earth is able to extract a pixel-perfect image from the training data (or anything even close, like that image but with some noise) using the weights of a large model. if this task is even possible, it would require a massive advance in interpretability. if anyone tells you something along the lines of "the ai takes bits and pieces from images it's seen instead of being creative like a human", they don't know that. they are lying. we straight up don't have enough knowledge about ai (or human!) internal mechanics to make a claim like this.
anyway i hope we can at least compromise that there do exist pretty clearly ethical models even in the "training models on unwilling peoples' work is unethical" framework, and that in general, its wiser to acknowledge what ai is capable of even if it means humans end up looking less special.

I think of it this way. I've spent years refining my art technique, making and marketing my own distinct style. And it's a very cutthroat business. Suddenly someone puts it into this weird gadget that can generate art that is identical to my style, without my permission, and does not attribute me in any way. I think I would be pissed.
Would you still be pissed if the gadget couldn't do it?
