those aren't packages

[ocean harbor]

well then how this works

without writing the package src; it gives me an error

¯_(ツ)_/¯

[south jasper]

with java, their are some main stream versions, most people don't install the new versions tell long in the future

java 8, java 11, java 17, and java 22, though most software out there uses java 8, so yeah java development is mainly centered around an old as f versions.

[ocean harbor]

uh im not sure about this

[junior hatch]

i haven't

[ocean harbor]

ahh I see

[flint thunder]

Really cool

[ocean harbor]

thanks

[solar hawk]

lol

switch to c++

[ocean harbor]

ive done cpp before java but now i forgor

[solar hawk]

ooof

[ocean harbor]

last project i did was integral area i think

gimme sec

it won't let me open it lmao

[solar hawk]

damn

[ocean harbor]

guess i can't access the code anymore

:(

[solar hawk]

thats crazy

[ocean harbor]

lmfao

[solar hawk]

repl money hungry.

im dissapointed

in replit rn

[ocean harbor]

lol

wait i think ive added it nowhere

in github

[south jasper]

C++ is freaking evil, life is too short to manage memory, espcailly using C++.

maybe because i got used to my garabage collector in java, but C++ looks stupidly and unnecessarily complicated, i feel like i can easily make unsafe code in it

[ocean harbor]

here's it

she gave me 92 to this project

[ocean harbor]

have you tried c# before

somewhat reminds of java vibes

[south jasper]

nope, but i heard it is the go to language for game dev in unity

[ocean harbor]

interesting

[south jasper]

and the syntax is similer to java too

[ocean harbor]

it is cringe but im gonna learn it anyway

[south jasper]

am planning to get into mobile dev

so it is swift/kotlin/java for me, plus some other cross plateform solutions

[ocean harbor]

give a try to groovy programming language if you haven't

it has java too

it seems easier tho

[solar hawk]

i used to mess w mobile dev

with react native

[pulsar pagoda]

[solar hawk]

whats this mean

is it an insult dandida

[pulsar pagoda]

yeah so

[solar hawk]

ok

[pulsar pagoda]

if u want to learn mobile development

dont use react native

[solar hawk]

i don't

but ok

[pulsar pagoda]

use it after learning native api's

[solar hawk]

if i need to make a mobile app randomly for whatever reason

i will use react native, because i am already familiar with it.

[pulsar pagoda]

also dart is a thing

and flutter

[solar hawk]

I won't learn mobile development for a one-time project

i am already comfortable with js,react, and react native so thats wat imma stick with

discord's mobile app is react native

also look what i found dandida

https://www.westerndesigncenter.com/wdc/documentation/w65c02s.pdf

@pulsar pagoda isnt it crazy

everything is already here

[pulsar pagoda]

is this for those small 8 bit processors?

[solar hawk]

yep the 6502

ima make the emulator

and then ill also know how to handle them when if i buy one

[pulsar pagoda]

have fun

[solar hawk]

dont u do stuff like this tho dandida

Does anyone know about algebraic patterns, I have a question.

[leaden torrent]

[lavish moon]

Oh sure you're the guy?

[leaden torrent]

it's more that we can't really help you if you dont ask your question, "algebraic patterns" is very vague

https://dontasktoask.com/

[lavish moon]

Yep so

It's a very vague topic, but it relates to dot functions corresponding to grid patterns on an x and y grid

So like a pattern of dots that specifically create pleasing geometric patterns to the eye and have controllable functions that directly correlate to an x and y only algebraic grid

[plain owl]

[mental basin]

Hi all! Could you please give me a hand about the following question?

for a measured quantity X, the $U = \frac{Xmax - Xmin}{Xmax + Xmin}$, if U’s error is required to be less than 3.5%, how about the resolution of X? Some one said X’s resolution should be 0.25%, which means $\frac{3.5}{\sqrt{2}*10}$ where 10 is a conventional requirement. Do you know why we need $\sqrt{2}$ ?

[distant juniper]

so i looked at the math curiculum of the university i'm looking to study in and there is a course that translates to english literally as "mathematical analysis" but i can't find any info on what "mathematical analysis" is in english. Does anyone know how to figure out what that course is?

so that i can look for materials on it

and see if i like university level math

i can give you example problems because they made the homework public

i'm guessing it's real analysis but i can't be sure

maybe later on they delve into complex analysis, i only looked at the first homework assignment

[river moon]

mathematical analysis is mathematical analysis in english

[storm sage]

Yes

If the math department of the uni offers a course called mathematical analysis, it is almost definitely real analysis. However, you could send a course description to be sure.

[distant juniper]

ok let me translate it just a sec

i couldn't find it on the website but here are the english books that confirm it is real analysis

V. Zorich, Mathematical Analysis 1, Springer Verlag, Berlin
R. G. Bartle, D. R. Sherbert, Introduction to Real Analysis, John Wiley & Sons
T. Tao, Analysis I, Hindustan Book Agency & Springer

[storm sage]

yeah those are all real analysis books

[distant juniper]

cool so i can study real analysis then

[clear parcel]

Tbh I don’t like the Tao books

makes sense though bc they are springer, and I haven’t found one good springer book

day 140 of hating java, let's go

[neat lintel]

gotta admit tho Baby Rudin is one of the best undergrad real analysis books

no wonder its so popular

been reading lately

one of the most enjoyable books I've read so far

[ocean harbor]

[neat lintel]

day 7651 of telling myself ill learn java eventually

[cinder zephyr]

Noooooo there are so many better languages out there

C++ for example

Or Rust

[neat lintel]

why should i learn C++ when i can just learn C tho

[cinder zephyr]

Because they’re different languages

Yes C++ is built directly as an evolution of C but they’re different lanaguages

Especially modern C++

[neat lintel]

I wonder what could one use c++ for?

I mean it's a widely used language in the industry but what about math people who know c++

[cinder zephyr]

Oh my god what could they not use it for

So many numerical libraries have C++ implementations

And graphical libraries

[neat lintel]

for some reason I think python is better than c++ for that (I admit this might be wrong)

[reef elm]

I like c

nice and clean

[cinder zephyr]

Again different use cases

[reef elm]

cpp code becomes hell

[cinder zephyr]

For example, Python is really slow

So if you need speed, C++ is better

But then if you only need to compute something a few times, speed may not matter

So the ease of Python (or SageMath!) will be good

[neat lintel]

where can I look at specific use cases of c++?

so I get a better understanding

[cinder zephyr]

I'm pretty sure the PARI computer algebra system is written in C++

[mental tiger]

this isn’t really math related

but are we made out of waves or

particles

[neat lintel]

[mental tiger]

i don’t get the slit experiment

it’s only a wave becomes a particle if it’s observed??

[river moon]

games, websites, search engines, robots, operating systems, etc

[neat lintel]

that's understandable, I was looking for use cases for mathematicians

such that c++ would be preferrable over python for example

[river moon]

these all involve math to a certain extent

maybe not websites

unreal engine is running on C++ (and you need your vector algebra, rotations, projections, etc)

you can do control theory while programming your robot on C++ and solve related control problems using C++ libs which would be faster than python

operating systems like linux used trees and queues to manage processes

programming a tree in python is hell

[neat lintel]

I understand this but I was wondering how c++ could be used by pure mathematicians working in academia

[fervent flame]

n/a

kekw

[river moon]

i don't think there's much math that pure mathematicians care about that it even has library implementation

[zealous garden]

Good thing Klein is available on C++

#discussion message

@wild lantern there’s definitely ways to spin things yeah

Just not like uhhh

Material projects or seminars given or anything easy

[wild lantern]

Yeah I gotcha. You could also probably weasel in some way to give talks, even if they're like solely within your school math club or something?

[fringe summit]

math club
Don’t exist really

If I get novel research, I could maybe do a lil grad student seminar, but uhh

Gotta get that

[wild lantern]

If you spam out a math talk on a department distro do you think you can get a handful of ppl to show up?

Not even talking about something that is actual novel research, like if you can swing that sure, but something more expository seems fine also?

[fringe summit]

I can’t just give an expository talk

[wild lantern]

Why not?

[fringe summit]

Because they don’t do those here

[wild lantern]

Tell ur dept to stop being cringe

Jk

[fringe summit]

Might be meeting w/ silly advisor tomorrow, so I’ll ask something then

[wild lantern]

Yeah, they'll probably have way better advice than me

[deep mango]

Any kind of student seminar or whatever

Would serve that purpose

[fringe summit]

Yes, for grad student novel research

That’s all they do here

[deep mango]

That might be giving it too much credit

[fringe summit]

There are no expository talks

[wild lantern]

Fwiw I was thinking there's bound to be a handful of undergrads and even profs that know nkthing of model theory that might be down to listen to you explain some of the basics

[fringe summit]

Right, I’ll ask something about trying one

There was 1 expository talk like

A year or so ago

On Brouwer’s fixed pt

[deep mango]

Im just not sure how you're figuring out what's expository. It's really really common for students to give talks on papers they're trying to understand for their research, not beginner level material but still expository

Like stuff that's exclusively in papers / modern

[fringe summit]

There are literally none of those

I’m saying there is nothing but presenting result

[deep mango]

That is very surprising unless the grad students are unusually productive

[fringe summit]

PDEs and optimization heavy school

[wild lantern]

I could see it unironically looking really good to have a talk aimed more at exotic undergrad or intro grad level topics rather than just research level results

[fringe summit]

Here’s so and so modification to this algorithm xyz

Here’s this slightly sharper bound

Oh right I need to email B (advisor-y guy) because scheduling conflict tomorrow

[fringe summit]

I’ll ask something about this though

[wild lantern]

Maybe they will be like "that's dumb don't do that"

If so bug them for better ideas lol

[fringe summit]

As I was typing this

He emailed about it

I’m the best there ever was fr

[fringe summit]

I doubt it on that one, given the earlier Brouwer one, but there’s not much expository ofc

There being 0 logic dept might make it a good move to

“Hey, y’all don’t study logic, but here’s some cool logic tech”

how do you convince your brain to just do it

try asking yourself why you want the degree in the first place

[oblique flicker]

I'm finishing my last year

like, i know that I have it in me

just one more semester, final thesis, and state exams and then I'm done

It's just that these courses are not really giving me anything and I don't care much for them (differential equations and topology)

It just comes with the studies

does anyone, like ever, actually have week-round consistent alarm times

[fervent flame]

or just have a chaotic sleep schedule

[oblique flicker]

i have an extremely fucked up sleep schedule now

[fervent flame]

do you mean every day of the year?

[fervent flame]

on this

maybe people in some prisons??

[sonic sentinel]

every day of the week most weeks, lets say

mayb

[fervent flame]

still, of course there are

people in the restaurant industry might have the same schedule every day

[sonic sentinel]

why restaurant specifically?

[fervent flame]

thats something i know of

maybe opening/closing managers for retailers

[sonic sentinel]

yeah but what about restaurant industry would make it prone to same day waking

[fervent flame]

if you own a (smaller) restaurant you might be getting up at a set time every morning to start prep

[sonic sentinel]

mmm okay

[fervent flame]

your premise is that the work has to be done every day of the week

which narrows the options to services that are open daily

[sonic sentinel]

i mean not necessarily

i was hoping maybe there are people out there who choose to wake up same time for health reasons

[fervent flame]

oh my b, i forgot you asked in general

there's definitely a sizeable population of military/ex mil folk who do this

also that unironic sigma grinder types

4:30 am alarm every day blah blah productivity

[sonic sentinel]

yeah im getting a bit into productivity stuff that's why i asked

i realized there's literally not like a single person i know who wakes up same time every day

What is the difference between state equation, characteristic equation and input equation exactly?

looking through my textbook those terms seem very identical

(Not quite mathematics related so asking here, and this is in relation to sequential circuits and flip flops)

[pulsar pagoda]

the state equation is given in terms of a sequential logic circuit

the characteristic equation is given en terms of the min sum of a combinatorial logic circuit

the input equation is how the flip flop behaves given its input to either maintain a its output or transition state

@neat lintel

it depends on the text book though

also state equation is kinda confusing, maybe use a state transition table

[neat lintel]

ok get that

[neat lintel]

of the min sum of a combinatorial logic circuit

so uh

i dont know if thats what my book describes it as

it is relating to the flip flop

itself i guess

[pulsar pagoda]

the flipflops themselves are just a component that uses combinatorial logic

the only thing that changes it is the clock input

as a enabler

maybe you want to study finite state machines a little bit before trying to make whatever ur trying to make with the flip flops

look into mealy and moore state machines

[neat lintel]

yes

thats exactly what im studying lol

[pulsar pagoda]

yeah that stuff is not hard

which book are u using?

[neat lintel]

okay so like

[pulsar pagoda]

ahh yes

so im right

the input equation is given in terms of what u need the next state of the input to be to either maintain the current state or transition

but thats SO badly explained in that phrase

give me a sec

[neat lintel]

the one made by Morris mano

okay so i guess like

[pulsar pagoda]

i found the book

give me a sec

im just trying to look for the appropiate figure

How do I know what a lump in my body feels like

Like the kind that get people worried about whether it’s a tumor/something to worry about or not

[solar hawk]

By ask doctor

[mint patio]

Yeah but it’s next to my balls and I don’t want to go pay two billion to the doctor’s office and have some dude feel me up if it’s just some stupid skin thing

If it’s a lump ig I don’t really have a choice which is why I’m asking how to tell if it’s a lump or not 😭 wtf is a lump

[vivid halo]

typically something hard and irregular in shape

in general if you feel something irregular that you haven't felt before I would see a doctor about this

true for lots of parts of the body

[jagged forge]

that image inspires fear in me the same way the diagram of testicular torsion does

[vivid halo]

same with possible skin cancer like if you see some kind of mole that you haven't seen before or you notice something much larger than before it's good to get that checked out and biopsied

[pure ermine]

hey are there any vcs in the server here?

[jagged forge]

i have like more than 50 moles

[vivid halo]

[jagged forge]

i have a mole in the center of my forehead too

[vivid halo]

I mean moles can often be benign

it's just something worth checking out if you get one growing quickly or one that is irregular in shape

[jagged forge]

and i have a large mole that made my doctor worry when i was like 8 lol

aren’t i too young to be worrying about skin cancer

[vivid halo]

not necessarily!

some people are prone to it, in the same way that some people are just more prone to developing moles

[jagged forge]

yeah, I heard people with lots of moles are sometimes more prone to it

so probably should be careful

[vivid halo]

moles themselves are not necessarily cause for panic but it's something you should keep an eye on and definitely get checked out if one is growing unually quickly or is irregular in shape

the irregular in shape thing especially is something that is cause for concern

[jagged forge]

i see

[vivid halo]

like this kind of thing

uneven color is also another thing

[jagged forge]

hmm yeah i don’t have any like that

[vivid halo]

that's good!

[jagged forge]

ok actually i just counted 80 on my upper body alone

[vivid halo]

[jagged forge]

and i can’t see my back

[vivid halo]

oog

[jagged forge]

yeah I’m fucked

nor my neck or face

[vivid halo]

definitely worth keeping an eye on

I don't have many moles but I get kind of worried about these kinds of things when something new shows up since I've had skin cancer in the family

[jagged forge]

mm

my mom’s sister had lung cancer and I think my mom’s parents had throat cancer

[vivid halo]

[jagged forge]

so uhhhhh no smoking for me lol

well this website attempts to classify your skin cancer risk based on how many moles are on your arm

their highest group is >11 moles

and i have >30 on my right arm

[vivid halo]

yeah definitely keep an eye on that

there are certain characteristics (irregular shape/irregular color/irregular growth) that usually mark the difference between benign versus malignant

and if you catch them early it's usually pretty easy to deal with

it's usually only bad if you ignore it

[visual breach]

What? You mean its normally not just a constant? 🥲

Like I don't think I've ever not been doing a differential equations module

[oblique flicker]

what are you talking about

[thick steeple]

I mean in my course we just have back to back to back differential equations modules for the first 2 years at least lmao

Like once or twice a week I'm doing differential equations

[oblique flicker]

oh

i mean they're part of analysis usually

also Numerical methods

but yeah this is a compulsory course for pure math just on diff (last year)

I just don't give a shit about it

it's not what I study math for

[thick steeple]

What area of maths do you like?

[oblique flicker]

Algebraic number theory, category theory

but I don't know lately

I feel so fucking dumb

[neat lintel]

hi

maybe if you take the derivatives of both and then do something

okay actually just write a function that describes the distance between both then minimize it

[tribal slate]

i was trying to find the the point on x^2 that minimizes the distance for a random point (a, 0)

i went wrong and its always (0, 0)

the line probably goes through (0.5, 0) tho

[neat lintel]

you could also draw a triangle 0,0, 1,0, 1,1 and then draw smaller and smaller triangles guessing inputs in between those coordinates and when the triangle gets bigger go back until you have a degenerate triangle with area 0

(that is a line)

the vertices of the triangle be constrained to be on the curves

maybe

i guess you would have to magically guess the right vertex on the curve with one vertex, maybe a quadrilateral XD

or just repeat the triangle thing with different vertices

and go up or down depending on line length

[visual breach]

One way to solve this is to find the normal lines on each point

And solve for when they coincide.

[gleaming panther]

I am in a conundrum

x/2x is some value but what if we use long division to calculate it
1/2
2x|x
-(x)
--------
0

So it equals 1/2
But what if we broke 2x into x+x, since polynomial long division takes the first value to see what it must be multiplied by to get the value inside, then apply that to the whole expression outside the garage shape(I forgot which one divisor and dividend is)

If we use that on this then we get:
1
x+x|x
-(x+x)
-------
-x

We have -x now so we multiply by -1

   1 - 1

x+x|x
-(x+x)
-------
-x
-(x-x)
-------
x

We have x again, so we multiply by +1, so based on this we know that we will always fluctuate between 1 and -1

So we have a series going 1-1+1-1+1-1+1-1+1........ so does this series converge to 1/2, because we do know that 1/2 is the correct and verified value for this statement.

I am wondering if we can use the Cesaro Summation and partial sums to find the value

But this series is divergent so this is weird.

I tried partial sums and keep getting 1 or 0, so if we apply Cesaro Summation and get the mean, we get 1/2 again

COOL!

But the fact that this is divergent still makes me uncomfortable

Does this also mean that we can represent series using division

I guess series are an endless process, and division is repeated subtraction

But this series also has addition

So wouldn't we need repeated addition, which is multiplication

I guess multiplication by 1 does not matter

But division by 1 is useless also

Hmmmm

This is interesting

since i have gotten a bit into that myself lately

my plan was to put 2 mellanox cards, one on my desktop, one on that mini pc i got

but the link speed was like 1/10th what it should be, partially cuz of the mini pc's specs

and then my main computers is windows which poses some obstacles...

so i just decided to buy a rackmount case and put two real computers in it, with actual full x16 pcie slots

[sonic sentinel]

imagine you are creating an AI to estimate, within its 90% confidence interval, any number given its description (i.e. "number of people whose names start with a vowel" might output [10m, 5b], let's say)

this description of the AI seems to be fine on the surface

; however, consider how you would test the AI

you could give it a list of descriptions with known numbers test whether the AI gets the numbers right around 90% of the time

problem is, if you have a list of descriptions with known numbers that you want the AI to get right 90% of the time, the problem just became trivial

(just make a range that includes 90% of the items in the data set; have a program output this in response to everything)

what is the actual solution to this? how would you define the goal for the AI so its actually doing something useful?

[fervent flame]

ah ic

they r sold out of the 149s

[jagged forge]

they have em on amazon in my country

[fervent flame]

yeah.... but then id have to actually do things

[jagged forge]

what, like replacing your mobo

?

[fervent flame]

i just want to buy, unbox and plug into the wall

[jagged forge]

fair

i went through a bit of pain installing my new hardware last month

but i feel more confident having done it a couple of times now

[fervent flame]

i know theoretically i can learn how to do it... i just dont want to, and ive already procrastinated doing it for 4 years lmao

it just sounds like too much effort for the first time

[jagged forge]

eh

the effort is not terrible

the worst part is just being nervous af about damaging things

particularly the cpu and socket

but it took me like an hour or two to replace the motherboard, cpu, fan, etc

im sure a pro could do it way faster

[fervent flame]

how much time did you spend looking stuff up

with regards to assembling

[jagged forge]

idk, i did it all during the process

the only really nontrivial part was installing the cpu correctly

.... and getting the damn power connectors to plug in

but it was mostly just follow the manuals

[fervent flame]

hmm

what made you get the 3080?

[jagged forge]

i couldn't hit 60 fps in elden ring lol

[fervent flame]

ah lol

was it the best you could get then?

i.e why not 40 series

[jagged forge]

it was the best i could get besides the 3090 at the time

40 series was not out yet

and the prices were still high

[fervent flame]

ah ok

[jagged forge]

i was not about to spend $2k on a gpu

i already had to spent $1k on the 3080

[fervent flame]

ic

im trying to decide which one i want

need to do some more looking up

ideally it would be nice to have good dl functionality

but i just want smth thatl hold for a while

im assuming any of the 40 series should be good

but at least a 4070 ti seems to be what i want

[jagged forge]

the deep learning folks seem to like having lots of vram

so they get 4090s

but the 4090 is so expensive

[fervent flame]

yeah, my research group has v100s which is nice

[jagged forge]

dayum

[fervent flame]

i think i mainly want something thats fast so i can work locally when theres a fire at the building or the it admin quits and locks us out for 2 months

(both have happened)

how important are cooling and power supplies stuff? they seem the most arbitrary in terms of metrics

as in, what is "good" vs minimum

[jagged forge]

depends on the cpu/gpu

i have an 850W psu and i would not feel comfortable getting a 4090

mainly because the 14900k draws a ton of power

also even the best air coolers can’t cool the 14900k at full load apparently

so basically i just looked at what cooler gamers nexus used in their benchmarks for the 14900k and got that

but honestly these days amd is just better and you’d be doing yourself a favor buying an amd mobo + cpu

they draw less power and are neck and neck, and the 7800x3d is the best cpu for gaming right now

7950x3d if you want more cores for work and top gaming performance, although it’s a few percentage points worse than the 7800x3d

[fervent flame]

hmm

yes ive seen that the ryzens are on top of all the benchmarks ive seen

[jagged forge]

yeah amd is pretty badass man

also don’t trust userbenchmarks, they are trash and anti-amd

[fervent flame]

lol really

[jagged forge]

yeah the guy who owns userbenchmarks.com has like, an irrational hatred of amd or something

they lowered the weight of multicore benchmarks to make intel on top

anyway for the psu i would just put your pc parts into a psu wattage calculator and buy based off of that

idk about the different ratings, i just get gold

because it sounds good? lol

[fervent flame]

lmao

okay ill use a calc

okay wait

the 7900 has more threads, but is worse

or

[jagged forge]

worse at gaming

i think only half the cores have access to the v-cache, which is what makes the x3d processors perform so well

[fervent flame]

ah okay makes more sense

[zealous garden]

I almost want one

Instead I'll be saving for a 5950X

[fervent flame]

whens that dropping

also does the case even matter

it seems like you just need to make sure things fit

but otherwise who cares what it is?

either way... with a 4090 its coming out to 3.5k

do i send it

wait i need a monitor and kb

[solid snow]

some have some features like more fan slots / better airflow but you should worry about whether it can house stuff first

[jagged forge]

it would be nice to fit a 420mm radiator… but it it would also be nice to not have an intel 14th gen cpu

@neat lintel what font do you use for latex?

[solar hawk]

is discussion 2 back to normal

[gusty sinew]

Hi

[vast surge]

@gusty sinew Can you describe the open sets in the discrete metric?

[gusty sinew]

Wdym by our open sets?

[vast surge]

Well if you're going to understand compactness

We need an open cover

And for that we need open sets

[gusty sinew]

Agreed

[vast surge]

So, let's take some set $X$ and assign it the discrete metric

Describe the open sets in X

Hint: Create an epsilon-ball with epsilon=1/2

[gusty sinew]

Alr, an open set is a set with every point being an interior point, and an interior point is a point such that below a certain radius, every open ball is contained in the set. In the discrete metric, the only open sets are single points I'm guessing since below radius 1, only the point itself will be having distance smaller than 1

[vast surge]

So you've found some of them

It's true that singletons are all open

But, remember, arbitrary unions of open sets are open

[gusty sinew]

Yes

[vast surge]

So that means every set is open!

[gusty sinew]

Amazing

[vast surge]

If $X$ has the discrete metric and $E\subseteq X$, then $E$ is open in $X$.

[fathom swallow]

Abelian Grapes

[vast surge]

How do we see this? We know singletons are open, and we can write $E=\bigcup_{x\in E}{x}$

[fathom swallow]

Abelian Grapes

[vast surge]

Okay, now let's address compactness

What's the definition of compact?

[gusty sinew]

No set is compact?

[vast surge]

Nope. But good guess!

[gusty sinew]

Every open cover has a finite subcover

[vast surge]

Right

So given some set $E$

[gusty sinew]

Oh, lmao single points are compact

[vast surge]

Yeah!

Anything else?

[gusty sinew]

Nothing comes to mind rn

[vast surge]

Okay, so here's what we'll do

[gusty sinew]

Im gonna take a guess and say finite sets are compact too?

[vast surge]

Yeah! Can you tell me why?

[gusty sinew]

Oh shit I'm stupid sorry

[vast surge]

Not stupid

[gusty sinew]

You just pick an open set that covers each point

[vast surge]

Right!

[gusty sinew]

Finite subcover obtained

[vast surge]

Yep

[gusty sinew]

Wait can't you just do this in any metric space?

[vast surge]

Yeah.

[gusty sinew]

The above argument

[vast surge]

Finite sets are always compact no matter the topology

[gusty sinew]

I just remembered that I had learnt it

[vast surge]

Okay, so my claim is, if $E\subseteq X$ is compact under the discrete metric, then $E$ is finite.

[fathom swallow]

Abelian Grapes

[vast surge]

And the way to see this is to use... Let's call it a minimal open cover; that is, an open cover where removing any set makes it no longer a cover

Given infinite E, can we find an infinite, minimal cover for E?

[gusty sinew]

Ah

Thats obvious

Or I have a counterexample rather, the set of singletons covering the infinite set

[vast surge]

Remember, in $\mathbb{R}$, the interval $[0,1]$ is compact but has infinite cardinality

[fathom swallow]

Abelian Grapes
