Why is there trans flag for math discord server lmao

faint light
#

oh my god…

#

trans flag has been there for like a year, the torus in front of it was just removed

crisp seal
#

because it is also a discord server and one where socialising occurs

#

In general all the decent discords are left wing and have a lot of lgbt people

blazing summit
#

Oh makes sense. Its a safe space for left and lgbtqia+ folks

#

👍

storm sage

Yeah the trans flag has always been here

#

Always as in like a year

blazing summit
#

First time seeing it, joined a while ago tho

It's not part of the April Fools stuff

This isn't even part of the joke

It has literally been here for months

#

The torus was also rainbow pride-themed

compact rune
#

Okay

#

Maybe I need new glasses

neat lintel
#

@delicate pilot a vector space has dimension n iff there is a basis of size n for that space. In particular a space has dimension 0 iff the empty set is a basis for it. Such a space has necessarily only one element called 0. And we have 0+0=0 and a*0 = 0 for all elements of the underlying field.

storm sage
#

and the flag is faint in the background so when we removed the torus it's way more obvious

compact rune
#

Anyways why a trans flat

storm sage
#

but I promise you it was there before today lol

But there is L, G and B left

Yeah they are also all welcome lol but we just picked one flag

#

There wasn't anything terribly deep behind it

The torus being rainbow is meant to signify all LGBTQ ppl

i always felt like up until a year ago there was a hobby i could say i was "into". like in my freetime i'd start doing this thing pretty much automatically and spend a huge chunk of my zoning out time thinking about it and whatever.

#

pre-2021 or so this thing was minecraft, like mid2020-mid2021 it was chess. after that i was very interested in math

#

but then like somewhere around a year ago i think it just stopped, and there hasn't been much of a "thing i'm into" anymore

i've realized that desmos is a simpler copy of geogebra

#

am i missing something?

neat lintel
#

Saying that is an insult to desmos lol

dire glen
#

geogebra seemed more complete

neat lintel
#

I mean sure geogebra has tons of additional tools as well but desmos just feels natural to use

#

At least to me

dire glen
#

but is very similar

#

is there some substantial difference between the 2?

#

that makes desmos better for you?

#

i guess it depends on the use case as well, for what i'm doing, graphing simple functions, both are overkill for me 😄

#

3d geogebra is more performant

neat lintel
#

I guess the handling of tools and interface makes it nicer to work with, at least for 2D graphs

For 3D geogebra is the king

dire glen

and you can link stuff in the graph and manipulate them.

For those who've taken Columbia Math Undergraduate Seminar 1 or 2, how much outside work is required (problem sets, readings, etc.) Thanks for your help!

vernal token
#

GeoGebra can't do that (or atleast for me, it didn't work)

#

Also it feels Desmos is generally a bit smoother, even if you sketch some "heavy" function, you can zoom in and out without much lag, which is not the case for GeoGebra

#

But Desmos seems to lack the (or some of the) CAS functionality GeoGebra has, e.g. I don't think you can integrate a function and make it show its function term in Desmos

#

You can plot the integral, sure, but you can't see the function term (though maybe there is some function for that, I haven't used Desmos much)

jagged forge

Desmos can do that

i'm assuming you want the expression inside the sum to be arbitrary

That sounds like it should work, but the person doesn't know english. Should i find a book we both understand? The person said that they can actually use google translate but that may get a little rough with mathematics. I guess since i speak the language i could help with the more math specific stuff

I have no advice for that but that sounds fine

Do you think i should try to find another book? Given that the language i speak doesn't really have that many good quality options

Uh, what class are you using Pigeonhole in? I just did it and found it intuitive enough. If you are using it for Advanced Abstract Algebra Analysis 11 (non hyperbole version: something further than discrete math), then I can't speak to it.

Prove that any collection of 31 distinct integers between 1 and 60 has the property
that one divides another.

discrete maths is fun if you figure out how to solve the problemn

quick beacon
# orchid badger like Prove that any collection of 31 distinct integers between 1 and 60 has the...

Informally, first, we can agree that including 1 is a bad idea because any integer is divisible by 1.

If we include 2 we have to exclude {4, 6, 8...}, and if we include 3 we have to exclude {6, 9, 12, ...}

We can get numbers above 30 essentially "for free" because they exclude no other values themselves, this gives us 31 through 60. However, any other value we pick will have one or more multiple of it within this range. We can exchange then, one for the other, but the best we can do for n values is n/2 values that don't divide each other. Thus pigeonhole.

Of course, if you suggested the problem you're likely already aware of the solution, but thanks for the fun challenge nevertheless.

Like by what number divide

#

Can’t all numbers divide by all numbers? Maybe it’ll be a lot of decimals and stuff but it’s possible right

surreal sapphire
#

this is in the sense of without remainder

#

divisibility only makes sense for non-units and if you work with real (or just rational) numbers, everything except 0 is a unit

#

(thats what you just figured out :D)

yeah but the data is in there i mean

sometimes it gets more creative than some ppl tho but still

it does mistakes event at a very simple equation

this is probably one of the cases where the 'creativity' (randomness) screws it, then

it has the answer but it changes something each time, so it's necessarily wrong

yeah, that result is wrong

you can have sums of the form $\sum_{n=k}^\infty \frac{1}{n^{1+\epsilon}} = \infty$ but not when the exponent is strictly larger than 1 + eps

the famous example where it's easy to show divergence is $\sum_{n=k}^\infty \frac{1}{n^{1+\frac{1}{n}}}$

# fathom swallow

but yeah, this result is true to the best of my knowledge, there's even two (three?) proofs of it, one being linked in the paper above, one being in the paper above, and a third i hazily recall seeing in a french paper somehwere

#

it''s probably possible for a sufficiently talented undergrad to solve themselves if they assume good enough bounds on the irrationality measure of pi

#

linear algebra done wrong my sergei treil, good book

dusky vale
eager ledge
fervent pebble
#

with low enough bounds you could probably find a 'low discrepancy subsequence' and from there the goal is to show that that sequence diverges

#

those also aren't my thoughts, for the record

#

i'm somewhat parroting something an old teacher told me while we were working on this

silver prawn
#

well (without reading the paper) if for example we're looking for instances where cos(n) ~ 1/n-1, we wouldn't need to look for distinct really good approximations to pi, bc different values of n might associate with the same really good approximation

#

but maybe this interpretation means the two issues amount to the same thing

#

What’s like the standard course progression after high school?

I know it’s like ode and calc 3, maybe more stats? But what’s past this

north topaz
#

So before you do ODEs (and PDEs) you would definitely need a course on differential equations in general, so like second-order linear DEs, Fourier series, reduction of order etc.

#

For pure maths you are definitely going to do analysis (real and complex analysis) and abstract algebra (groups, rings and fields)

#

These also then branch out and specialise, so differential geometry, topology, and functional analysis for analysis

#

Galois theory and representation theory for algebra

#

And then you of course have statistics, so after a first course in uni statistics (where you learn how to use R in addition to learning about ANOVA, t-tests, pooled means etc)

#

You would then do a course on prob and stats, so distributions and maybe Markov chains

vivid halo
north topaz
#

And then you would do further stats such as Bayesian inference, further ML (maximum likelihood) stuff

vivid halo
#

if you're more on the applied side of things some more statistics/PDEs/numerical methods is typical

north topaz
#

Have a look at this: this is typical for North America

#

Europe is quite a bit different

glass peak

#

In terms of when you do courses (it's earlier) and how much of your major you devote to just maths

river warren
north topaz
river warren
#

i cant get a math minor with my degree if i take diffyq

glass peak
#

that’s what DE is

north topaz
#

Also keep in mind that you could do stuff with mathematical physics, or econ / quantitative finance, or maths related to computer science such as machine learning, or mathematical biology even

#

There's also a lot of applications and crossover with different fields in STEM

#

'Applied maths' is an umbrella term and it doesn't do justice to how diverse the field is

river warren
#

yeah

#

mainly its bridging the gap between math and application

#

you dont necessarily need doctorate level math, people just study theory cuz they like it

north topaz
#

Yeah the use of mathematics in applied maths is only 1/3 of the process

#

1/3 is about representing the problem mathematically: defining key concepts using maths

river warren
#

usually a not math centered undergrad stem degree will make u go up to calc 3 and linear algebra

north topaz
#

And 1/3 is about interpreting the results in your given context

river warren
#

but then its applying it in physics and materials

north topaz
#

Or like a requirement to become a maths teacher

#

People have different goals in life yk

river warren
#

cuz mechanical/aero math only goes up to linear algebra

river warren
#

in undergrad

#

cuz

#

like

#

fluid dynamics

#

thermodynamics

#

incompressible flow

#
