i mean thats a given lol

#

aside from good grades, research, internships, get close with few profs

dense hornet
#

I screwed up the part with getting close to profs

#

I might just try to talk to as many as I can about how well they know me

fervent flame
#

what year are you?

#

i didn't really get close to any until my jr year

#

it helps if you've had a prof for a few classes

#

Most of my Profs are Aerospace profs.

For me it’s because paper back is cheaper. Didn’t read any previous texts but I just saw this question lol

forget a rule on a math test. yeah that was me on my calc final so i tried proving it
the teacher gave me credit anyway because i used like a page and a half of paper in the attempt opencry
i was unsuccessful

paperbacks because I can turn over the cover page (and hold the book in one hand) as opposed to hard-covers

Wdym by autobracketing?

Okay so I have macros that cycle between [] -> \{\} -> () -> [] and macros that cycle between [] <-> \left[ \right] and \{ \} <-> \left\{ \right\} and () <-> \left( \right)

#

Which one are you asking for?

#

You have the global options setup right?

Put this inside global

Yw! Do take care of indentations inside global.
Also, important point, to trigger the snippet, type : after ) or ]. So for example, typing (abc): will output \left(abc \right)

#

Ok so what is combinatorics

#

Broadly speaking

#

It's counting things

#

@tame egret

tame egret
cinder zephyr
#

So generally you have some (typically finite) structure with some rules

#

And you want to see how many of these structures exist given these rules

#

For example, how many ways are there to order n district objects

cinder zephyr
#

Versus n not necessarily distinct objects (say you have m objects of type A and n - m objects of type B)

#

Yea

#

And the beauty of the subject is that you can count the same object in multiple different ways

tame egret
cinder zephyr
#

And get nice proofs of formulas

tame egret
tame egret
cinder zephyr
#

So you could prove this formula by induction

#

But there's a nice combinatorial proof

#

Say we have a set of size n, what's one way to create subsets?

#

For each object, we make one of two choices

#

Include it or don't

#

So that's 2^n choices

#

But also we could just count the number of subsets of size 0

#

n choose 0

#

And then the number of subsets of size 1

#

n choose 1

#

etc etc

#

And sum that up

#

And we get the left hand side

#

So we've enumerated through the same set of objects (the subsets of a set of size n)

#

In two different ways

#

And we've gotten a combinatorial proof of that equation

#

@tame egret

#

Those kinds of arguments are IMO the spirit of combinatorics

tame egret
#

hmm

cinder zephyr
#

Makes sense?

tame egret
#

😕

cinder zephyr
#

What's confusing you lol, no shame in being confused

#

I make no claim of being a good teacher

tame egret
#

nCk = n!/((n-k)!k!)

#

then

cinder zephyr
#

I'm not really using that definition

#

But yes that is the formula

#

I'm just using n choose k = the number of ways to pick k items from a set of n items without caring about order

Hello everyone,

I'm currently working on a statistics problem involving a table with the following data (Dummy Data):

X

1

2

3

4

5

I need to calculate various statistics such as mean, standard deviation, and variance for this dataset. I usually use online calculators like Calculator Soup (www . calculatorsoup.com/calculators/statistics/mean-median-mode . php) for single-row data. However, I'm facing difficulties when dealing with multiple rows.

If anyone could provide guidance on how to adapt these calculators for multiple rows or suggest an alternative website or method to handle such scenarios, I would greatly appreciate your assistance.

Thank you in advance for your help.

yo guys did i understand the collatz conjecture correctly?

1. Start with any positive integer n.

3. If n is odd, multiply it by 3 and add 1.
4. Continue until n is equal to 1

it's really a matter of whether you like the subject, have the resources to study it, and are in an environment that facilitates this

there's not a concrete metric to say whether someone will be able to contribute to mathematics like euler or gauss did

most people can probably learn not just basic arithmetic

not reading the paper but 99.9% chance its crankery

i have also not heard of either of the organizations the authors are supposedly associated with

#

but "the blyth institute" looks a lot like a predatory journal

#

charging $100 and $250 "membership fees"

just based on these facts alone, i am fine dismissing it without even reading the abstract

#

if you want to read the contents and verify their mathematical accuracy yourself, go for it.

leaden torrent
#

if a paper claims to have a new result and ends up there, thats the arxiv editors saying "even though we formally dont check preprints for their quality, we can tell this is bullshit"

#

the only legitimate stuff on math.GM is stuff that does not claim to be novel mathematics research

#

so like, expository papers aimed at a general audience, or short articles outlining the life of a mathematician

#

stuff like that

#

(and even then, a lot of it is crankery about how ramanujan divined numerological patterns from the stars or something)

#

(but there is legitimate stuff in there as well, its just not where mathematics research gets put)

bronze wedge
#

expository etc?

leaden torrent
#

field-specific expository stuff usually still ends up in its appropriate subject tag

#

but if youre expositing on like

#

intro real analysis

#

they arent gonna put that in the analysis section

#

which isnt a dig against it, just indicates that its not of interest to the type of people likely to be following the mathematical analysis tag

#

which doesnt mean its illegitimate, just not relevant to any of the subject tags

# lavish kayak i remember chemistry has an "evolving lie" education strategy i.e. they tell a r...

my issue with this strategy is that very natural questions aren't answered in the book and my textbook is really unwilling to say "we aren't going to deal with so-and-so for now" or "there are different conventions but we will use this one".
like for example they talked about ionic radii and a google search i made showed up that there are different methods for calculating ionic radius by assigning proportions of the inter-nuclear distance(idk what's the term) to each cation and antion in a bond, but the different methods all give rise to some of the same periodic trends. it was interesting and not hard for me to understand, but the textbook is just like "ions have radius and these are the trends." surely they can try harder??

Is there a way to mathematically frame the game of chess on a standard chessboard so that you can transform the board into any other homeomorphic shape and get the corresponding movements of the pieces on the new board?

#

Question inspired by this YT short

#

From what I can tell I think he just made up the rules for how the pieces move on this new board

#

But like what I mean is you mathematically formulate how the pieces can move on the given topology (if that makes sense)

#

Then under some homeomorphism of the board, idk say a circle, you can get corresponding transformations for how the chess pieces “should” move on the new board

vivid halo
mint patio
#

What

#

Yeah but what does “normal” mean here? On a square shaped board the knight can move in an L shape. It doesn’t do that on the circular board; moving at an L would land you on top of two different squares at once

vivid halo
#

you move according to the grid here

#

as you would in normal chess

mint patio
#

Yes, so can you model that mathematically? Like you define a function specifying the spots it can move to (and how it gets there), then when you transform the board you can apply the same transformation to get the equivalent movement on the new board

vivid halo
#

I mean sure I guess

mint patio
#

What about fucked up board shapes? Wouldn’t there be shapes such that there’s no “logical” (you used the word “normal”) way for some pieces to move according to the new grid? I have no examples for this, intuition just tells me it’s a possibility

#

Well I guess not actually lol

i have slightly over two times my parents' apartments monthly rent rn (this apartment is for four people, including me)

#

allowance per week is 2.5% of rent, but that includes school lunch money, so im probably getting around 1.6-1.9% rent excluding lunch money

#

i don't remember the history of the allowance though

#

looking up, it seems like normal allowance rates, unfortunately it gives me no info on what those allowances include (parents might have their kids pay for clothes, etc)

When I was a child I remember of having seen the ending of a film where this kid was in the world of his imagination or something, and some creatures appeared: there was this plusman or negativeman (I don’t remember exactly) and the latter was the enemy I think. At the end the kid wakes up and it turns out he had just slept in the middle of the math lesson.
Does anyone know what the name of this film may be?

@vast cipher helo niku s

#

sorry for random ping xd

#

i just wanted to ask you something regarding MATLAB because last i heard u were pretty knowledgeable at it ThonkSpin

neat lintel
#

ok so basically

#

im making an app in app designer

vast cipher
#

oh geez

#

i have no idea about app designer

#

use R KEK

neat lintel
#

the thing relies on a table from excel, but i realised that having it be an absolute reference is dumb because im gonna be submitting it catThimc

so i like

#

made this

#
[fileName, filePath] = uigetfile('*.xlsx');
key = fullfile(filePath, fileName);
#

but idk how to like idk make it a global variable if that makes sense? because i have two functions that need to use the key variable but putting it in both just makes the the thing request user to put the excel file twice lol

neat lintel
vast cipher
#

why not just make an object with all these important things as attributes

#

then pass that object to your other functions

#

idk youre pretty far beyond how id normally use matlab tbh

#

i would recommend using R

#

unironically

#

but i have no idea how complex the thing youre trying to do is

#

I wish i could merge matlab and rstudios app maker

neat lintel
#

yeah thats alright

vast cipher
#

oh wait

neat lintel
vast cipher
#

wait

#

i dont get it are you saying when you call a function that relies on key it triggers the uigetfile call again?

neat lintel
#

yeah

vast cipher
#

👀

neat lintel
#

like i will show you the code i have

#
methods (Access=private)
    function encryptedMessage = transmitter(app)
        % Input the Excel file
        [fileName, filePath] = uigetfile('*.xlsx');
        key = fullfile(filePath, fileName);
        % Read the tables
        englishTable = readtable(key, 'Range', 'A2:Aend');
        encryptedTable = readtable(key, 'Range', 'B2:Bend');

        % Convert tables to cell arrays
        english = table2cell(englishTable);
        encrypted = table2cell(encryptedTable);

        % Get user input
        userInput = app.Type.Value;

        % Encrypt the message
        encryptedMessage = '';
        for i = 1:length(userInput)
            index = find(strcmp(english, userInput(i)));
            if ~isempty(index)
                encryptedMessage = [encryptedMessage, encrypted{index}];
            else
                encryptedMessage = [encryptedMessage, userInput(i)];
            end
        end
    end

    function decryptedMessage = receiver(app, encryptedMessage)
        % Input the Excel file
        [fileName, filePath] = uigetfile('*.xlsx', 'Select the Excel file');
        key = fullfile(filePath, fileName);
        % Read the tables
        englishTable = readtable(key, 'Range', 'A2:Aend');
        encryptedTable = readtable(key, 'Range', 'B2:Bend');

        % Convert tables to cell arrays
        english = table2cell(englishTable);
        encrypted = table2cell(encryptedTable);

        % Decrypt the message
        decryptedMessage = '';
        for i = 1:length(encryptedMessage)
            index = find(strcmp(encrypted, encryptedMessage(i)));
            if ~isempty(index)
                decryptedMessage = [decryptedMessage, english{index}];
            else
                decryptedMessage = [decryptedMessage, encryptedMessage(i)];
            end
        end
    end
end

ok woops

oh no i think you honestly are coding more advanced than i normally would

something like

    function encryptedMessage = transmitter(app)
        if isempty(app.excel)
            [fileName, filePath] = uigetfile('*.xlsx');
            if fileName == 0
                return;

hi guys I'm taking an analysis I/II with elements of linear and abstract algebra too. the course is incredibly hard (last year only 3 students out of 200 passed). there are little to no calculation exercises (solving limits, studies of functions, etc) as the exam is only made of exercises on proofs we have to come up with and text problems that require some degree of reasoning. what are your tips on how I should approach this exam? do you have some recommendations for textbooks with exercises of this type? thanks

plain owl
#

You should have homework problems

#

Make sure you can do those

#

If you have lecture notes, read through them

#

If you can do all the homework you should be fine

#

The low passing rate might be due to the wrong people taking the class

and is going crazy fast

#

#

Something has to have gone wrong in the lectures

surreal wave
#

plain owl
surreal wave
#

ok anyway

#

how do i prepare?

plain owl
#

Being able to do the past exams is also good preparation

#

Probably the most efficient

surreal wave
#

because out of all the textbooks i found i can only find calculus exercises (solving limits, studies of functions, etc) and no real analysis exercises

plain owl
#

Do it a couple times and time yourself

#

Get a study group if you can

surreal wave
#

yes but i dont understand shit lol

plain owl
#

Look up convergence criteria for the series

#

For the limits you should have a theorem/lemma in lectures about ratios of polynomials

#

That only the highest degrees matter

#

For convergence criteria you will mostly need 3, one with roots, one with ratios and one about alternating series

#

Functional analysis, specifically C_0-semigroups

plain owl
#

For example

#

Also some others, but PDEs most common yeah

surreal wave
#

im gonna study on christmas day

plain owl
#

Don't think so

surreal wave
#

i wanna cry

plain owl
#

I wrote my master thesis on irreducibility in Banach lattices

#

I did apply it

#

For example i characterized irreducibility of the Dirichlet-to-Neumann semigroup

#

A Banach lattice is a Banach space with a linear order on it such that the supremum of 2 points exist

#

Virtually all function spaces you can think of for example

#

Scratch linear order

#

Partial order and it's an ordered vectorspace

#

Eh sure, thqt's one line in latex

And especially not modern democracy

A democracy is a system of deciding who governs

@delicate tide in fact, earth is actually a black hole

#

there are a lot of things on the surface of earth that capture light

#

most obviously plants

sonic wind
#

and photosynthesis causes the plant to travel through time

#

...ok yes this is absolutely ridiculous

delicate tide
#

earth is 3D

sonic wind
#

ok more seriously

#

why would being able to capture light suddenly make something 4D

delicate tide
#

you're twisting my words

#

and i can't be asked reiterating

sonic wind
#

...ok wait so looking back at exactly what you said

#

when something bends time enough to capture light, that makes it 4d

#

because of... travelling back in time...? i don't see how that's relevant at all

#

and also i still don't get why that would be the cutoff

delicate tide
#

and i corrected my self

#

saying forward in time

#

you cant travel back in time

sonic wind
#

(...well actually you can if you allow FTL)

sonic wind
#

but ok yes if you travel faster than light then relative to some observers that means you travel forwards in time, i don't really know how that relates to anything about black holes so i'm just going to ignore it

sonic wind
#

Spacetime is four-dimensional

#

so yeah nothing special about black holes, just, they're spacetime, and spacetime is 4d

#

that doesn't really explain anything about the view that black holes are 4d and earth isn't, earth is also a region of spacetime

delicate tide
#

you won't be able to find any scientist or physicist saying that earth is 4D

sonic wind
#

i think i probably could

delicate tide
sonic wind
#

i mean yes it's linguistically ridiculous to include time as a dimension of arbitrary physical objects, but it's not any less ridiculous for black holes?

sonic wind
#

it's just a random aspect of semantics it doesn't matter

delicate tide
sonic wind
#

if you can't actually say what 4d means with a definition by which black holes are that, then you weren't actually "taught" anything other than which sounds certain people make

delicate tide
sonic wind
#

is there any observation you could make involving a black hole that you would expect to have different results depending on whether it's 4D or not?
