im summer schooling my geoemtry credits

to take trig next year

and then pre calc year after

and finishing school off

with calc

or ap calc

[carmine dirge]

how's it going guys?

I always do what I have to do

[tulip void]

How do I use $50,000 to enhance my looks to attract more women besides limb lengthening surgery which I may seriously consider getting

Hello Guys!

best resources for statistics?

[true zinc]

At what level of study?

Undergraduate, Grad, etc...

[urban rivet]

i have stats in my undergrade but didn't study

and i want to study for my postgraduate

[true zinc]

okay by postgrad do you mean like going for a Masters or PhD or even beyond that

[urban rivet]

master

[true zinc]

Have you studied real analysis yet?

[urban rivet]

basically I am doin master in operational research

Coming from tech background

[true zinc]

Okay

Our uni requires courses on stochastics, probability, etc...

so we'll give you books on those topics

[urban rivet]

yeah

My first sem:
Linear programming
Python
Queuing System
Inventory Management
Statistics

Goin to join university from next week

[true zinc]

if you don't mind sharing, can you tell us what uni you're going to (you can say in DM's if you want) so we can check their syllabi for the classes?

[urban rivet]

ok

[urban rivet]

check dm

[true zinc]

done

[true zinc]

Have you taken real analysis yet?

(via a book like Abbott, Rudin, etc...)

[urban rivet]

Nope

[true zinc]

Well at this point I think just Blitzstein and Hwang's stat110 book is all you need if you need to refresh undergrad probability, if they go further, then we can suggest more advanced readings

[urban rivet]

Thanks bro for ur help

[carmine dirge]

thank you bro

you talk too much

[true zinc]

me?

[north topaz]

is this a joke

if you have 50,000 you should save or invest it

50,000 can still pay off college if invested

[unborn meteor]

[north topaz]

depends how much risk you want to take

50,000 in US government bonds can still become 100,000 in 20 years

https://www.bloomberg.com/markets/rates-bonds/government-bonds/us
yeah 10 year is 4% annual yield

[neat lintel]

erm

[carmine dirge]

fine.

[patent bone]

hlo

[solid snow]

What the fuck?

Dont recommend tren to people

Fuck is wrong with you

[true zinc]

1. what is tren
2. why is that person recommending it

[solid snow]

its a steroid

but its normally used to juice up cattle

it has insanely bad effects on the body

[true zinc]

Oh

That is

why would someone recommend that yikes

[glass peak]

I mean it does get you huge

Just at the cost of like years of your life and your general health

[jagged forge]

and your testicles

[glass peak]

Do they permanently shrink or is it just while your test levels are like 200x natural?

[jagged forge]

that’s a good question, i have no idea

[old oak]

For the aspiring minotaur 🐄

[leaden skiff]

Oh is it that bad? 💀

I have a friend who uses tren and he was pretty casual about it

[true zinc]

it totally fucks your body

[leaden skiff]

How badly

[solid snow]

very badly

[fresh comet]

I found this to be pretty interesting

https://www.youtube.com/watch?v=-QBFsdAdfwo

[neat lintel]

Well, that's cool, I'm really happy for you

[white temple]

no way people actually use tren

[idle narwhal]

pretty sure it can go back to normal + if you take HCG along with it then it can help avoid them from shrinking

[loud snow]

Freaky

[flat cloud]

do you think all undergrad math can be self taught from internet/books?

I wanna learn all math I can but its too late to change my major lol

this is mostly directed at courses like complex analysis, algebraic topology and such

[fresh comet]

yes

[verbal karma]

most yes. some is tricky to get the right sources

unless one can read any books, then sure you can self-taught

[north topaz]

a RealLifeLore video said that if civilisation were to start again, it would be in Bangladesh

[fresh comet]

[north topaz]

it's crazy that half a billion people fit in a circle with radius of 450 km tho

just that part of the world alone

and also some of it is ocean

half the world

[fresh comet]

indeed, the density is insane

[verbal karma]

I hate the circle under this projection

[north topaz]

I watched some more related videos

and starting in 2050 or something the world population centre is going to move west

by 2100 it will be in Saudi Arabia

cause of Africa

[carmine dirge]

that's so boring

[valid ibex]

react to this song Hanumankind- Big Dawgs

[carmine dirge]

yes that's it

[neat lintel]

You’ve said this like 5 times

[rapid kiln]

@wise bloom hey
have you noticed that most of the people just ask questions in Help Forum and then disappear

[quick beacon]

I've noticed.

[wise bloom]

Yes

[quick beacon]

But it's fine

[wise bloom]

See bro

Anyone will

Most of the times help reaches late than in the help channels

[rapid kiln]

that's kinda lame
I've checked about 100 forums now, and only <20 are somewhat solved

[wise bloom]

Yes

I k that

I feel people post their queries to get immediate help but it often leads to the opposite

In the help forum

The only solution to this is either we equalise the help forum with the channels or we increase the no of channels i mean like double or triple it

And also decrease the timeout time so that channels refresh faster after getting solved

[rapid kiln]

There are many hidden channels
what are they for?

[wise bloom]

Maybe I am wrong and it's only for the helpful?

Idk maybe u need a specific role to access them

[rapid kiln]

idk I can't access it

maybe it'll be something else

[wise bloom]

No i feel

It's a refreshing chamber or section

Where after the help channels get closed

They refresh and then come back to

The

Original help section

That's why it says hidden maybe?

I am not sure

Which is true

[rapid kiln]

I've never seen those numbered channels being used

[wise bloom]

Idk

Opinions on stimulant use in math?

specifically adhd style medications (prescribed of course)

do they provide an advantage to learning?

[gusty socket]

well, if you have adhd they certainly can help you focus. i don’t know (because i have NO data, even anecdotal) whether it helps people learn if they don’t have adhd

[north topaz]

if the opioid crisis told you anything, it's that stimulants aren't worth risking your life for if you're not the person who needs them to function

[sonic sentinel]

i already finished ap calculus ab as a school subject should i try to see if i can skip my normal math classes in grade 12 :P

cause the school lets you skip physics if you took ap physics 1

me and my friend took calculus one year earlier, so possibly we could lobby the principal into giving us a free period as in ap physics

the alternatives are (1) study stats instead of calc (2) take calc class but ask for reduced tasks

the stats teacher is already very laid-back so i think it would be the better of the two options

but im not sure if taking stats in school is worth it

in summary the three options are (1) stats (2) calc but slack off a bit (3) slack off entirely

[solid yarrow]

me ._.

[austere cipher]

if your school offers the BC section of calc BC as a full year course at your school, you should consider taking it, becuase calc BC only covers 1 or 2 months of content. It's a good option if you're not planning on taking the test

[obsidian leaf]

What did you guys do for entertainment in high school? I find online games quite fun and connective to other online people, but it seems to affect my memory of academic subjects like maths/chemistry/biology…

[unborn meteor]

"seems to affect"
i code

and play games

ofc

[obsidian leaf]

y laugh

[unborn meteor]

if you're gaming during class you don't hear the teacher (unless you're good)

[obsidian leaf]

I'm talking about your free time at home or break time at school...

[unborn meteor]

ah

i don't have a problem forgetting stuff

when i code or play games

[sonic sentinel]

i am taking calc bc, but it won't show up in my report card

my school "offers" calc bc as in they'll do a course audit for collegeboard and i self-study but occasionally consult with the calculus teacher

[austere cipher]

💀

[sonic sentinel]

im not sure if this counts as abusing the course audit system but i think its based of the school cause its useful to be able to take aps

Any course that a school labels “AP” must receive authorization through a process called the AP Course Audit, which confirms teacher awareness of course scope and occasional exam changes, and ensures that confidential practice exams and other resources are only accessible to real AP teachers verified by a school administrator.

^this makes it sound like what my school is doing is within the system

[austere cipher]

did your class do the same curriculum as the BC calc curriculum?

[sonic sentinel]

i took ap calc ab

that's what i meant in "taking calc one year earlier"

ap calc ab has a proper teacher and classes and everything

(but its after school cause my school is shit 💀)

[austere cipher]

so, you're gonna take BC calc and an additional math class next school year, becuase the BC calc class doesn't show on your transcript?

[austere cipher]

☠️

[sonic sentinel]

im gonna take BC but its not gonna show up on my report card. i can choose to take stats or calc, but i can also probably convince the principal to let me skip math classes for senior year altogether (since i already have enough math credit). if i choose to take (essentially retake since i learned everything) calc classes, i might be able to negotiate a lower workload. if i choose to take stats, the good thing is that the teacher is laid back so additional workload isn't much of an issue.

[sonic sentinel]

oh my god i was taking eight hour-long classes in a row with like 10 minute break to eat lunch while everyone was getting an hour long recess and goes home after six hour-long classes. im surprised i survived 11th grade.

it's worth it now though if i can skip two classes daily

[austere cipher]

💀

[sonic sentinel]

honeslty im glad school is over soon

i want my summer break to end quicker so i can just get through 12th

never had that feeling before

[austere cipher]

you still got 2-8 (more if you want to be a doctor) years of college left man

[sonic sentinel]

true

[austere cipher]

Most of the things taught in school are just hard to retain if you’re not constantly practicing and applying what you’ve learned.

[austere cipher]

I’m good in the gaming department. Wish I could improve on the coding part

[unborn meteor]

what coding do you alr know

[austere cipher]

Print(“this is all I know”)

[unborn meteor]

first, use single instead of double quotes

[austere cipher]

💀

[unborn meteor]

why nerd emoji

im not a nerd

[austere cipher]

I don’t like the look of single quotes. Reminds me of every time I got points off for poor spelling in English class

[unborn meteor]

try syntax highlighting

makes em look a lot better

i use https://vscode.dev for school coding

and then i use WRECKED for running the code

[austere cipher]

I wish I knew what that meant

[unborn meteor]

this stuff works on school chromebook

[austere cipher]

Bro, my school blocks all the actual IDE because kids kept doing malicious stuff with the code

[unborn meteor]

this is where my bypass kit comes in

[austere cipher]

💀

[unborn meteor]

which blocking system are they using

"malicious stuff" script kiddies detected

[austere cipher]

I got no idea, I’m not really a computer science guy

[unborn meteor]

like how do they block stuff

do they use goguardian, securly, lanschool, or what

[austere cipher]

No idea

[austere cipher]

I don’t really want to jail break my chromebooks anyway

[jaunty niche]

is even like repl.it blocked?

[unborn meteor]

it's not jailbreaking

my tech is completely sandboxed in the browser, the way they like it

[unborn meteor]

replit has copyright problems so its banned everywhere

[jaunty niche]

oh just a proxy of some sort?

or more complicated

[unborn meteor]

not even a proxy

its a program that runs programs

[jaunty niche]

huh right

[unborn meteor]

WRECKED = Working Runtime Environment Creation Kit Enabling Debugging

file:/// uri based program

[hardy iron]

School blocking things in general is dumb imo

[unborn meteor]

yeah, so easy to bypass

the district is out for me

[hardy iron]

My uni never blocked anything on their ethernet

[unborn meteor]

lol

[stiff barn]

.

[ocean harbor]

I think that's just their stupid internet

so they block stuff

[tidal prairie]

Hi

[fresh comet]

hi

[astral bay]

@left pewter just moved the convo to here, how do you like the remarkable tab? helpful for self-studying math?

[left pewter]

I've had it for 3/2 years and I love it, I had a 50cm stack of notebooks before and now I can carry 100 times that in my hands

((not based on calculations))

[astral bay]

nice, i was looking at those

i have a couple wacom tablets

they were super cheap on eBay

[left pewter]

It's also great for reading papers and articles! If you don't have a printer/want to print everything out

Ooo

[astral bay]

i cant stand printing

[left pewter]

Because it's too much paper?

[astral bay]

yeah, it's just too much clutter

i've got enough stuff already

[left pewter]

Yeah it would become a lot after a short while if you don't recycle it regularly

[astral bay]

right

how do you think the remarkable compares to a iPad?

[left pewter]

Hmm well in which aspects?

[astral bay]

taking notes, and reading book specifically

[left pewter]

Both have an internet connection, the ipad has apps (including browser) while the remarkable doesn't, taking notes and reading I think work well on both, the main difference being that the remarkable doesn't emit light and is relatively dim (even compared to paper, not a huge difference tho) unless you have a bright light. The pro with that is that it's so much easier on the eyes, the con is that you need a good light source

I don't own an ipad personally

I've heard you can get a screen protector that makes it more paperlike to write on

[astral bay]

i wonder if maybe i can pick up a remarkable used on eBay

[left pewter]

Perhaps

[astral bay]

man, those are expensive, even used

someone gave me an iPad

[left pewter]

It cost me about 420 dollars to buy it new, but honestly it's been one of my best purchases even though I'm a poor student

But

[astral bay]

can you export a PDF off of the remarkable?

[astral bay]

its totally worth it i would think! especially in your scenario

[left pewter]

If you have an ipad it might be good enough for you!

Depends on what you think

[left pewter]

Yeah

You press a button and it sends it to your email

[astral bay]

how do you get content onto it?

[left pewter]

They have an app on both desktop and mobile

On desktop you just drag and drop

One of the main criticisms people have on the remarkable is that it comes with an optional subscription service, so if it's important to you that documents are synced indefinitely between the remarkable and the app or that you can access stuff via google drive then you would need to subscribe to that

[astral bay]

cool, do you happen to know if it works with Linux? i am using ubuntu

[left pewter]

I haven't and it's not been a problem for me as everything I would do on paper works perfectly well

[left pewter]

It doesn't unless they've introduced it lately, but you can upload stuff to the remarkable on the web instead

[astral bay]

oh yeah then it wouldn't matter what OS you have

hmm, thanks for answering these questions, ive been curious about remarkable for a long time, so its good i talked to you

[left pewter]

Not really, the desktop app is just a bit nicer

[astral bay]

maybe i will start bidding on one and get one for a low price at some point

[left pewter]

No problem :^)

[astral bay]

because the wacom tablets do just fine

[left pewter]

Hope you can find one at a reasonable price

[astral bay]

also, i have a GPD win max, if you know what that is

i can write on that

so if i need to go portable, i can write code, read PDFs, and take physical notes on the touchscreen

[left pewter]

Ooo I haven't heard of that

[astral bay]

its just a small laptop

but it has a touchscreen

[left pewter]

Woah, handheld gaming laptop

[astral bay]

https://www.amazon.com/GPD-handheld-controls-keyboard-touchpad/dp/B0CZTRCXP4/ref=asc_df_B0CZTRCXP4/?tag=hyprod-20&linkCode=df0&hvadid=692875362841&hvpos=&hvnetw=g&hvrand=2204022693760740604&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9015346&hvtargid=pla-2281435177818&psc=1&mcid=5cc0811cccfb30dfac099289ee6d8b67&hvocijid=2204022693760740604-B0CZTRCXP4-&hvexpln=73&gad_source=1

yeah it's cool, i use it for doing math though, and writing code, not for gaming lol

[left pewter]

That's really nice for coding at different places hehe

[astral bay]

yeah it's cool, and it's really good for an airplane

because it fits on the tray table

[left pewter]

Oooo yess

I would love that when I used to work on programming projects all the time

Before university 😢

[astral bay]

when im learning math, i like to code as many of the problems as possible, to keep up with coding skills at the same time

any calculation related problem, i write a python program to do it

or R

[left pewter]

Ohh nice!

Yeah I've been using julia & matlab to code up smaller things

[astral bay]

yeah if you're interested in that sort of thing, you should check out Jupyter Notebook and Python

oh there you go!

that's awesome

[left pewter]

It's different from working on a project though heh

[astral bay]

oh for sure

[left pewter]

It's so fun to have a bigger idea and work towards it

But it takes A LOT of time

[astral bay]

agree

[left pewter]

Which I used to have

[astral bay]

you will have it back when you finish your degree(s)

[left pewter]

Hopefully, at least partly

[astral bay]

but you can just integrate the coding in with anything really

there isn't much that coding can't help with

[left pewter]

Yess that's part of why I chose to study space engineering instead of computer science

[carmine dirge]

hey guys let paly this

[astral bay]

yeah smart

i wish i had thought like you when i did my degree

[left pewter]

I want to apply my programming skills to different areas and widen my knowledge of other stuff

But I am occasionally curious about computer science stuff that you learn in university

[astral bay]

i think you can just pick up a book or do leet code programs for that

[left pewter]

I only have knowledge from programming projects and reading online and nerding about between ages 14-18

So like the practical part I have nailed down, I spent like most of my free time on it for many years

I know too much about c++

It's more the theoretical parts and more low level stuff I lack

But yeah I should find some interesting book hehe

[astral bay]

if i were you i would enjoy your time in college, and dont rush to join the industry

i miss those times

[left pewter]

Well now I don't really feel like working as a programmer. I'm much more scientifically and mathematically inclined nowadays and want to do something good for the planet and not some random company

But enjoying my time in college I do because I love to learn

[astral bay]

enjoy man

[left pewter]

Thanks, will do :^)

[quasi jetty]

Please do not advertise your help channel or thread in other parts of the server. There are many people who need help, so advertising can quickly turn into spam.

[unborn sleet]

@flint plover hey you still got an issue with that exercise?

[carmine dirge]

hey

[urban rivet]

Hii!

Can anyone tell me why square in variance formula```

[unborn meteor]

because then it lets you easily multiply and add variances idk

[urban rivet]

why square? not mod?

[unborn meteor]

again idk

[true zinc]

this I think

[urban rivet]

why not mod ?

|x-xbar|

It's like sqrt(2+2)==sqrt2+sqrt2

[gusty socket]

that's not correct

[urban rivet]

i also think

[urban rivet]

.

[true zinc]

this is very wrong

sqrt(2+2) = sqrt(4) = 2

sqrt(2) + sqrt(2) = 2.828

[urban rivet]

i know i am generally saying

because the square root of variance ends up being the std. deviation that doesn;t means that

[true zinc]

we literally had this discussion in general chat a bit ago, f(x+y) = f(x) + f(y) is only valid for linear operators

[gusty socket]

i think they're agreeing with you

[true zinc]

oh

[north topaz]

well most people don't use mean absolute deviation, an alternative way of thinking about the variance where we don't square, but we take absolute values of the differences to the mean and add them all up

check that out if you're interested

[haughty panther]

like i said in discussy, check https://en.wikipedia.org/wiki/Cauchy's_functional_equation
it has pathological nonlinear solutions but there's only nonconstructive proof

[true zinc]

alr

[neat lintel]

They're still linear over Q tho

[haughty panther]

yeah they are expected to act rationally on Q

[quiet geode]

is modular arithmetic linear algebra in 1D?

[prime plank]

the integers modulo any prime is a vector space over itself

[quiet geode]

i dont understand

i am shit

sorry for wasting your time

[unborn trellis]

Z/pZ is a field, so it's a 1D vector space

But modular arithmetic is not linear algebra

[quiet geode]

is it a subset

subset~ish

[unborn trellis]

I mean, you can do linear algebra over these finite fields

This is something people study extensively

So you'd be interested in Z/pZ-linear maps between vector spaces

[quiet geode]

im interested in

wine

[unborn trellis]

[quiet geode]

please

ive had a terrible mathematical experience

[unborn trellis]

So in what sense were you making the analogy between 1D linear algebra and finite fields

It seems like you actually have good intuition lol

[quiet geode]

Thank you maam, i think im gonna cry

i think i vibe too much with math (very loosely)

at this moment i dont know what a vector is and i dont know what modular arithmetic is

yet

[unborn trellis]

You're onto something, keep it up 🫡

[quiet geode]

i cant, i think ive lost it, thats the painful part

really appreciate the words of encouragement though, ive not had a good time

[loud snow]

Vector= https://despicableme.fandom.com/wiki/Vector

Modular arithmetic = 🕰️

[quiet geode]

all of jumbled mess couldve been sorted had i figured a way to relearn it as how a 4 year old would do

i need to reset my brain somehow and still be me

[loud snow]

Consume brainrot

[unborn trellis]

If it's any consolation, I was nearly failing math in high school until I started getting motivated

I have a failed math test pinned to my corkboard to keep me humble lol

[quiet geode]

its not even about failure in instituition at this point, cant care any less about them

its my mind

I really appreciate it though

LIKE REALLY

[unborn trellis]

I get that though

I really didn't think I would even graduate from college until I started tbh

As a mind thing

[quiet geode]

Ive tried to relearn stuff but it almost feels like the past experiences are influencing too much with what im TRYING to learn

youd be surprised by the number of times ive asked what is a vector in this chat and walked away with satisfaction and yet somehow i again dont know anything

my feelings about them isnt that straight forward

i havent passed anything and yet somehow an honourable thinks i have good intuition

IT MOVED ME

SERIOUSLY

thank you guys, imma head out

ive had intuition about equivalence classes

you guys gonna make my eyes wet again no way

by thinking about a question that goes

why is 5 in set of natural numbers needs to be equal to 5 in the set of integers

if you get the point of the question

youll get what im trying to convey

boring answer

it need not to be

Equal

we have MADE it equal

actively

[gusty socket]

it is not, actually, if you are trying to break it down set-theoretically. integers are equivalence classes of pairs of integers :) (the equivalence classes are given by (a,b) \equiv (c,d) if a+d = b+c in N)

[quiet geode]

this is real analysis i think

[unborn trellis]

blud pulled out the grothendieck group

[quiet geode]

blud

🤣🤣🤣🤣🤣

[quiet geode]

the sets are sort of constructed in such a sophisticated manner that it will not disturb the already existing grassroots of mathematics that allows things to be consistent

[gusty socket]

grothendieck copied ME! I'm touched, really

[unborn trellis]

the smay group

[quiet geode]

hence we decided to make 5 in N equal to 5 in Z

[gusty socket]

some would disagree

[quiet geode]

Oh yeah Norman Wildberger definitely would

[unborn trellis]

We can construct both sets and write down an injection from one to the other in the obvious way, which is what I would formalize what you're saying as

[quiet geode]

i like him though

[quiet geode]

yes, thats what professor did as well

[gusty socket]

no, i mean like if you are trying to be pedantic about what it means to be equal, then someone who is familiar about how Z is constructed would say that the set N and the set consisting of positive elements of Z are not equal. there is only an injection from N to Z (see: bacono's message above me)

[unborn trellis]

He's a bit of a crank among mathematicians, just for your information

[quiet geode]

i cant think about stuffs again, my mind isnt allowing me to, i simply can engage FUCK

[quiet geode]

oh yeah ive followed him for years

he thinks the foundations are oxymoronic

[unborn trellis]

What we're saying is that the formal process of identifying a set as a subset of another set is done through writing down a 1-to-1 map from one to the other

So 5 in N and 5 in Z are equal because 5 in Z is the image of 5 in N under this mapping

[unborn trellis]

most notably, I think he just outright rejects notions of infinity

[quiet geode]

yes

ive wrote stuff about things like these before, i cant believe i wrote it myself as i can no longer understand anything in them

[unborn trellis]

I think the fact that you're thinking about ideas like this deeply is great

This is the essence of understanding formalism in mathematics

[unborn trellis]

God I remember in freshman year of HS I had a huge crush on this one girl, I literally never talked to her and then one day I asked her on an outing after feeling brave and she said "thanks but I don't know you"

[quiet geode]

zamn

[unborn trellis]

In retrospect, that was the obvious outcome lol

Moral: be normal and have normal relationships with people before you ask them on an outing

[quiet geode]

Yes exactly

ive been writing pages worth of otherworldly shit to email to her lol

while having 'be normal' on the back of my mind

[unborn trellis]

I'm gonna say probably don't cold email her with pages of otherworldly shit

[quiet geode]

yes been contemplating this all evening

[gusty socket]

lol

[quiet geode]

thankfully i have never had this sorta experience before (approached only one girl before and had a really normal relationship)

like as normal as it can get

i was happy i managed to pull it off so nicely

Laid back attitude

[unborn trellis]

I also remember thinking in high school "I think I'm pretty normal, I don't think I'll look back at myself and cringe"

[quiet geode]

oh yeah that happens all the time

i was insanely sensative to that

until i got mentally disturbed outta nowhere

[quiet geode]

thats all i have left now :sobsuncontrollably:

[quiet geode]

someone else told me its measure theory the other day

[unborn trellis]

Probability theory is built on measure theory yes, but I mean philosophically how we interpret probability

Frequentists believe that probability says "if I repeat this enough times, the ratio of successes to failures will converge to the probability"

[quiet geode]

the name made too much sense to me lol

[unborn trellis]

Bayesians think of probability in terms of priors and known information

[quiet geode]

i just can't appreicate this currently.

im pretty sure i wouldve loved this

my situation is so fucked

im neither an engineer nor a mathematician

[unborn meteor]

ok so

well i have 2 black hole ideas

first one is to generate power

second one is orion drive

[true zinc]

Also, speedy I think the reason we haven't tried to literally harness black holes is because either A: it's currently impractical and/or B: we don't know how to

[unborn meteor]

there is a theory that extremely small black holes are produced in particle collisions

[true zinc]

not to shut you down, but we have a feeling some particle physicist somewhere would have already tried to run the numbers before

[true zinc]

I thought they created antimatter

[unborn meteor]

oh i'm sure

they also do that

depends on what collisions you're doing i think

could you make a gun

that shoots high energy hadrons together

to cause decent sized explosions

a hydrogen bomb?

[unborn meteor]

for that size you need quetta eV levels

hand grenades

you only need like 10 TeV

assuming ttb hadron

ok what about this

what if we somehow captured all that energy

then we can

shoot protons together

the mass of the protons is converted into energy

the gain of this is like 1.0000000000001x the energy you put in

[slow jewel]

what is that?

[quick beacon]

I can try.

[trail granite]

helllo evry1

[wooden falcon]

Usually yes. It’s noted for its use of LEM.

[quick beacon]

But I need to go soonish

[quiet geode]

can someone talk boolean algebra with me

isnt boolean algebra sorta qualitative analysis more than quantitative analysis

is it in any way a truer reflection of operators in hand (qualitative)

[quick beacon]

boolean algebra is just algebra on values which can only take two states.

in other words, it's applying the ideas of "addition" and "multiplication" to true and false.

@quiet geode

[alpine kindle]

I mean

[wooden falcon]

Yes. A boolean algebra is the same thing as a commutative F_2-algebra

[alpine kindle]

you aren't usually doing addition

[quick beacon]

that's why I put them in quotes

[alpine kindle]

usually boolean algebra is AND and OR

[quick beacon]

you're using and and or

which and maps to multiplication and or maps to addition

[alpine kindle]

"or" doesn't behave like addition

[wooden falcon]

AND, OR, NOT as a gateset are equivalent to +, * for addition modulo 2 and AND

[alpine kindle]

the actual operation that works like addition is xor

[quick beacon]

Yes, I know

[quiet geode]

this is like the stock standard definition

[wooden falcon]

Well it does behave like a kind of addition. But if you forget NOT for a moment and consider the structure with OR, AND. It will be a rig (or semi ring) rather than a ring.

[quiet geode]

please talk more along these lines

its like say

OR is the same as +

you arent worried about the exact value

1+3 = 4, 1+0 = 1

it is just that addition 'increases'

[tawdry pecan]

it can be looked at that way, but why would you

[quiet geode]

because why not lol

whats better than operators that are consistent across bases

or atleast they are already consistent but only their qualitative part and not their quantitative part

its sorta also like the idea of abstraction we used in relations and functions

aRb, depending upon the exact nature (qualitative and quantitive) of R we will determine the order of a and b in a set

when i break the abstraction with a>b or a<b i also can now determine the order of a and b in the set

so by breaking abstraction of the relation (quantitative abstraction), i can determine the order of its operands in a set, similarly if i break the abstraction of a and b with constants, we can pay the relation back by letting it categorise in reflexive, transitive, symmetric or any other

boolean algebra feel similar

only difference is numbers with different bases are involved

is this making any sense at this point?

[quiet geode]

more like once its reflexive, transitive, symmetric or anything else for that matter, it would remain consistent regardless of all a and b

how to think clearly

[quick beacon]

if we're using F_2 we can define AND as multiplication, XOR as addition, and OR as the sum of AND and XOR. i.e. OR: F_2xF_2 (a,b) -> F_2, a * b + a+b. We can test each possibility. (0, 0) -> 0 * 0 + 0 + 0 = 0, (1, 0) -> 1 * 0 + 1 + 0 = 1, (1, 1) -> 1 * 1 + 1 + 1 = 1

and now it's just F_2 with some custom function names.

[quiet geode]

what even

[vivid maple]

1+1= 3

[visual breach]

Does inclusion exclusion principle measure difference of OR and + on F_2

[quick beacon]

you know, that's a good observation. I think you're correct, but I've never considered it in that way

[wooden falcon]

Definitions you just have to know else you can’t parse anything else. I learn these by learning to understand what the definition really means, and motivating it through a healthy stock of examples, and also why it’s the definition we take rather than something else.

Proofs. I never try to memorize proofs. I learn techniques, I learn to understand the techniques and what’s generally useful, I remember the techniques by using it over and over for different proofs (this just happens naturally while doing math, I don’t even need to do separate practice for this).

Axioms to me are almost always just definitions.

Corollaries, lemmas, theorems always fall into the same bucket and are differentiated by vibes, they’re theorems: In general I don’t remember these and often go back to reference them as needed. Instead I have gotten good at recognizing the theorems that are really important to an area and just learn those theorems really well. Everything else I just learn to prove on the fly as needed or to try to generally piece together different results using as few necessary as possible. This way there’s very little to remember and what I do have to remember I use all the time which makes it even easier to remember.

Hi all

Got a great question for science lovers.

If i make a coil pancakes like make them to act 2 electromagnets

Can i make them to work like one inside other ?

Watch this video and asnwer. Me pls ping me.

https://youtu.be/AjUB-kYciDU?si=sTj8OOUXIxdlZeD4

Like make one to work as a below electromagnet

And using 2nd above electromagnet to levitate the 2nd electromagnet.

Like the voltage can be something that the electromagnet cant melt down.

Next step
Using super capacitors and capacitors make a pulses of high voltage which can make that electromaget device jump higer and stay in they air.
Might look something like vibrating in the ground if its wrong frequency.

If we use a frequency that can synchronize thats gonna work
"Anyi gravity" device.

lmfao i took a CS class in undergrad that had one pdf for the question, one png file for the figure but with boxes that said things like "value [a]", a separate pdf with a list of all the values, and a .tex file we needed to fill out to submit

for every question (except the .tex file was shared across questions)

i am assuming it was structured this way so that the same question could be given with different values to different students?

to prevent cheating? idk though we only got one shared "instructor solutions" pdf

maybe it was for reuse across semesters???

[hasty plover]

Hello, I am comp sci and maths 3rd year at Uni and I am looking for people to learn discrete/pure/abstract maths with me, we can work on proofs together since a lot of these books don't have solutions and we could make our solutions, also this subject benefits a lot from learning it with a group to discuss things. I am currently reading Proofs: a Long-Form Mathematics Textbook by Jay Cummings. DM me if interested.

[thorny orchid]

hi, is anyone familiar with the triangle inequality for the norms of the differences of matrices. I have a non-trivial problem I am trying to prove

$| A-B|{F}\le | A-C |{F} + | C-B |_{F}$

[fathom swallow]

Alex

[sly jungle]

Doesn't a norm satisfy triangle inequality by definition?

[thorny orchid]

Yes but here A and C are fixed. We are free to choose B given some constraints that limit the search space

constraints being that norm(A-C) = X and norm(C-B) = Y

[sly jungle]

I don't get it... maybe I am missing something. But you want to prove the expression you posted above? which is the triangle inequality?

[thorny orchid]

Sorry I haven't give the full idea I am considering. I have Hamiltonian that is formed by interaction coefficients eta_i which is a list of num_qubits - 1 numbers. The individual numbers have specific +/- locations that have been specifically chosen (for eigenvector decoding but not relevant here). In this example, H_1=A, H_3=C and we are trying to find H_2 such that it simultaneously satisfies norm(H_1-H_2) = X and norm(H_2-H_3) = Y for fixed X and Y. Essentially, H_1 and H_3 are formed by eta_i coefficients that are different in magnitude but have the same positivity/negativity. We need to choose some eta_i coefficients for H_2 that ALSO obey the positivity/negativity of H_1 and H_3.

My dilemma is, are we restricted in the search space for H_2 because of the sign constraint? Or because we can vary both norm(H_1-H_2) and norm(H_2-H_3) continuoulsy individually by just changing the magntiude of the H_2 eta_i coefficients, then there is no restriction?

[visual breach]

So your "norm" does not satisfy triangle inequality?

[thorny orchid]

thats precisely what im trying to determine

[visual breach]

Ahh, I see, so deciding if triangle inequality is respected

[thorny orchid]

yes, given this sign constraint

[visual breach]

I think you should ask in more specitic channel. Hmm

Maybe #advanced-analysis ?

[thorny orchid]

ah okay, will do if i have no luck here

Hi

[neat lintel]

I feel bad when I see other people talk about topics in math I know much less about. Since I'm so slow at learning, feels unreachable for me to reach that level

Do other people feel same way?

[neat lintel]

This is probably a really bad attitude to have, and the fact I have this attitude makes me think of myself as flawed and makes it all seem even more unreachable because of my flaws

[fresh comet]

yes, all the time

but I’ve gotten better at managing it over time

[fresh comet]

mhm

[gritty crater]

One person can't know every topics in math, tho. So that is quite common

[fresh comet]

this is something I’ve struggled with for a long time in general (not just math)

[neat lintel]

What helped with getting better?

[gusty socket]

yes, but i try to follow my own advice that i say to people, which is to realize that everyone is somewhere, and it's okay to just stop and appreciate the things that you find beautiful right now without having to "reach a level"

and that's really what math is about (you will get better just by talking about the things you find meaningful in math)

[fresh comet]

realizing and accepting that it’s okay to not know, and that it’s okay to be “slow”. mathematics is not a race or a competition, after all

[neat lintel]

It's not just about an abstract idea of "reaching a level". More like. There are things I find very interesting but I don't have enough background to explore them. And then I find myself stuck at things that should be elementary and feels really frustrating and like I'm so far away from ever getting into those interesting things.

For example, I've heard about stuff like manifolds admitting multiple smooth structures, and that sounds quite interesting. But then to do something as basic as proving the stereographic projections of S^n give a smooth atlas it took me like 30 minutes and I kept making mistakes

[jagged forge]

i don’t feel bad i just feel awkward lol

i have limited time these days and i’m not a mathematician so i don’t worry about knowing everything

but i do end up feeling like an awkward bystander in many discussions

[wooden falcon]

I used to. But not anymore.

[neat lintel]

I should probably stop feeling that way too, as it is likely a disadvantage

I should use my energy to learn more math, not to feel bad about knowing too little math

[wooden falcon]

Yeah we have limited time and can’t learn everything. Best to just be happy with what we can learn.

[fresh comet]

this is something I still need to work on myself, but I’m getting there step by step

[wooden falcon]

Imo it’s really cool we get to experience it at all. So much of this math just didn’t exist last century.

(or if it did, not nearly in as elegant of a form as today)

[thick yacht]

Last century meaning 1999?

[wooden falcon]

Yes

[neat lintel]

same here, especially when they happen to be younger or at an earlier stage of education

sometimes I'm open about how I feel about myself and the same people keep reassuring that I'm not so bad (math people are super supportive) which actually helps a bit

[maiden girder]

I never accepted “not knowing” and being “slow” i dont think ill be able to any time soon

[fresh comet]

but you surely cannot know everything

there's just too much mathematics out there to know it all

[jagged forge]

i accept that i will probably never know what stacks are

[fresh comet]

you have to accept that there will always be some parts of it you will never know about

this is not to discourage you

it's just how math is in this century

[neat lintel]

Not if I never die

[fresh comet]

hmm

do you expect to live forever?

[haughty panther]

i don't think it should be thought of in categories of advantage or disadvantage
like, it's not a competition, as long as you can sustain yourself somehow then it's already good

since you already know some areas of math well it means that you are capable of learning the ones that interest you, even if it takes some time
just enjoy the process

[neat lintel]

I'm not thinking of it as competing with others but as the cool things I hear about and would like to work with seem so far away

And if I don't work more efficiently I may never reach them

[neat lintel]

I really don't feel like I know any area of math well. I know some elementary stuff in many areas but nothing very deep

[haughty panther]

you won't reach some things as it's impossible like higher said
you just have to accept it ig

[neat lintel]

So far I haven't reached almost anything

[haughty panther]

giving up on goals and dreams is painful but sometimes necessary
though i might be biased as i have already given up on all of them 😅

[haughty panther]

you might have not reached whatever you want to eventually reach
but you surely made some progress

[neat lintel]

I don't have anything that gives my life purpose other than math so if I give up on that I don't know what I'll do after

[haughty panther]

just do what you enjoy
doing maths just because it's interesting and not because you feel the need to achieve something is very liberating

How deep are you in this book? Any highlights?

"its none of your business" lmao what a chad

[vast wraith]

just a couple dozen pages in, it reads quite sincere and i like his sense of humour, but i definitely haven’t gotten to the meat of the book yet

[brittle socket]

I see

[vast wraith]

ahaha

What I did not learn was how to study, or, for that matter, what studying meant. I was just barely smart enough to know that it did not mean memorizing—but I did think that to have learned something meant mainly to remember it.

Most of the content of my first-year mathematics courses is no longer taught in respectable universities; a part of it is relegated to high-schools and the rest is forgotten. Is that good? I don’t know, I really don’t.

[jaunty ibex]

I can

[vast wraith]

[potent nacelle]

find them online

facebook marketplace also works, some people give away old used books

nice people in my area

[wheat raft]

do you have MTW?

[neat lintel]

it's real that a big part of people who reach Phd level then leave academia due to difficulties in finding a job?
(which pays to live)

[inland patio]

just becomea. professor

easy

[sonic sentinel]

i just realized rock paper scissors has more than one nash equilibrium

randomly picking between paper and scissors with 50/50 probability can't be beat

[versed agate]

doesn't that lose to always scissors?

[sonic sentinel]

oh shit you're right

bruh

bruh i need to get more sleep

[icy locust]

doesn't that lose to energy drinks?

[vast wraith]

what

thanks hayley

[wheat raft]

sorry, Gravitation

by Misner, Wheeler, Thorne.

amazing book

[north topaz]

rock paper scissors is about reading body language

[sonic sentinel]

theoretical RPS

if you're leaking information, have limited computation, and can't pick options with uniform probability then yeah the game is gonna become complicated

[digital hill]

a bit embarassed to ask but how do i start off with studying math? like at this point i've realised i'm just a dumbass who can't understand all this jargon and i don't rlly get all the material i've learned from school intuitively

[gusty socket]

https://www.khanacademy.org is what i usually recommend, don’t worry about the “grade level”, just start where you’re comfortable.

and ask a bajillion questions because part of learning is interacting with people

unless you want stuff beyond calculus

[digital hill]

ic tysm for the advice and reccomendation man

[gusty socket]

one caveat, you HAVE TO do the problems

[gusty socket]

otherwise it doesn’t work

[digital hill]

well i'm currently studying precalc and i feel like i'm cooked 💀

[gusty socket]

okay, then this is the right resource

[gusty socket]

you have to do a lot of problems (i really can’t emphasize this enough)

[fresh comet]

you're capable, all you need to do is practice a lot

[digital hill]

yeah that's what i'm gonna do man nothings better than getting hands on experience after all ty again

[fresh comet]

and the best way to practice is to do problems

[digital hill]

where do i get practice problems n all? is there a good site for it?

[fresh comet]

Khan Academy itself should have many problems

[digital hill]

nvm i'll try getting a grasp of stuff first bfr asking again 😭

[fresh comet]

no, you should use this discord server to ask for help

we do not care and do not judge people for their background in math

this is a safe space

[neat lintel]

safe space

[fresh comet]

you object?

it should be a safe space for all

if something is making you feel very uncomfortable, you can DM @polar panther if you're not in a hurry or ping mods if you are

[rich dock]

the set {9/8, 3/4, 1/2, 1/3, 2/9, …. } what is the formula to get the next succeeding numbers

anyone goated can help

[fresh comet]

you should open a help channel for math questions

see #❓how-to-get-help

[neat lintel]

its multiplying by 2/3 every time

holy fuck i was reading the first one as 8/9 for some reason and i got so confused

a_n = (2/3)^(n-1) * 9/8

thats your formular

your secret formular

but its not secret because

i just said it

[rich dock]

wow ur the goat thanks

[R.L. Moore] was teaching a class in which several of the students were obnoxious and unruly. So one day he walked into the lecture hall, opened his briefcase, took out a pistol, set it on the table in front of him, and then began to lecture as usual. He had no further trouble with the rowdy students.

america moment 😭

probably not true though

[ocean harbor]

precalc is easy if you used calc

that's what I did

[light needle]

when he says students were obnoxious and unruly

he probably had some racismi n that

moore is a well known pos and racist

[old oak]

Studying while Black

That said, whomst among us hasn't fantasised about murdering their students at one time or another

[old oak]

Except for cranks
