I’ve used a base 64 encoder to talk to my friend on a server

It’s like an organization site I used for a server and

And they couldn’t use Discord or anything

So they talked to me through there

#

i think you last said what it formally was? I cannot find the comment

hollow gale
mellow geyser
#

let's decompose that statement

raw cedar
rocky shuttle
hollow gale
fresh oriole
#

here’s the definition given in Pugh:

A cut in Q is a pair of subsets A, B of Q such that:
(a) A U B = Q, and A and B are disjoint and nonempty (i.e. A and B are a partition of Q)
(b) If a in A and b in B, then a < b
(c) A contains no largest element

raw cedar
fresh oriole
#

the definition HChan gave is essentially that of A (the other set B is determined from A, so it’s not strictly needed to be mentioned)

hollow gale
#

im trying to avoid talking about sup and inf lol

mellow geyser
#

if it is, it would make sense why it's called a "cut"

fresh oriole
#

I’d say it’s from (a) and (b)

hollow gale
#

yes, you are quite literally cutting the rationals down some point

#

and defining a real number as the bottom half of that cut

#

that's why it is called a cut

mellow geyser
hollow gale
#

it is necessary to remove duplicates

viral oracle
fresh oriole
#

so for example there’s A = {p/q | p/q <= 0 or (p/q > 0 and (p/q)^2 < 2)} and B = {p/q | p/q > 0 and (p/q)^2 > 2}

fresh oriole
viral oracle
#

npnp

#

I had just come across an exercise in analysis asking for a proof of this (or something similar? I'm not sure if it is identical because:) for the reals but not the rationals

mellow geyser
fresh oriole
#

property (b) is meant to encode that A is completely to the left of B

viral oracle
mellow geyser
viral oracle
#

I think maybe it would be easier to describe the cut property as two nonempty, disjoint subsets A and B, with A U B = Q (or R), and a < b for all a in A and b in B

mellow geyser
fresh oriole
#

yeah because otherwise they could be disjoint but all mixed up alternating back and forth

fresh oriole
mellow geyser
hollow gale
#

ignore the R

#

just think about it as Q

viral oracle
#

oh then I'm mistaking what this is about

#

ignore me then

fresh oriole
mellow geyser
viral oracle
#

the definition I stated is a property of the reals, so since you're specifically talking about Q and constructing R from it, then yeah that would not work as well

fresh oriole
#

yup. It’s larger than everything in A, but smaller than everything in B

mellow geyser
#

Ok, this get's us one irrational number, but how does it guarantee that we can do it for all irrationals? Because I notice that it wouldn't work for something like pi

hollow gale
#

why wouldn't it work for pi?

mellow geyser
#

because pi isn't the root of a rational number

#

not just square root, any rational root

hollow gale
#

well, that just means that you cannot explicitly describe what the cut looks like

#

but it is in there somewhere

raw cedar
hollow gale
#

just like how you can't actually describe most real numbers but there are still there somewhere

fresh oriole
#

it’s less obvious how to express pi in this way, because we aren’t allowed to just use the pi symbol to make the cuts

raw cedar
#

there are multiple monotone series for pi.

fresh oriole
#

unless we’ve defined pi elsewhere already somehow

hollow gale
#

yeah, most conventional definitions for pi employ the use of sine and cosine

#

which need the real numbers to work

#

any series definition would be somewhat unconventional

raw cedar
hollow gale
#

it works but this goes against the sprit of the question

raw cedar
#

indeedddddd

mellow geyser
hollow gale
#

can you tell me what you understand a dedekind cut to be?

mellow geyser
#

from what I understand: of a set Q, a dedekind cut is the element of Q \ A \ B, where A and B follow the properties we discussed

serene vault
#

just seeing this, thank you! catlovechristmas

hollow gale
#

can you spell them out for me?

mellow geyser
#

A and B don't share any elements. Every element in A is less than every element in B

#

am i missing anything? this is how i understand it

fresh oriole
#

almost, except Q \ A \ B is empty

mellow geyser
#

wow. This one is interesting

fresh oriole
#

the cut is the pair A and B itself

mellow geyser
#

it sounds like root 2 shouldn't exist then

hollow gale
#

I don't know what Manifold is saying

#

the cut is specifically A

raw cedar
#

it did not exist before the construction.

raw cedar
fresh oriole
# hollow gale the cut is specifically A

I’m following Pugh where he takes it to be both, but from what I understand we could equally well take either one by itself, since the other is uniquely determined from it

hollow gale
#

I'm trying to make it easier to understand

mellow geyser
hollow gale
#

but since you're confident that you can do it then i will take my leave, enjoy

mellow geyser
#

rt2 isn't in either set, and Q \ A \ B is empty, right?

fresh oriole
#

and once that’s done, you can prove the square of this cut equals 2

mellow geyser

hollow gale
#

it is annoying me that people are responding to my comments with um actuallys

#

i don't think he did it with that intention

#

it's fine, I'm done with this

#

BACK TO TOPIC

#

we need more people for discussion

#

ill go recruit some from math discussy

mellow geyser
fresh oriole
#

so, the definition of a cut is quite elegant, but this is where things get messy

placid shadow
#

What are the rational numbers? Just any number that’s not irrational nor complex?

fresh oriole
#

eh, maybe it’s not so bad

idle steppe
raw cedar
#

yes! so like 2/3 or 5/6

idle steppe
serene vault
#

(that's why they are called rational)

raw cedar
#

no wai

placid shadow
idle steppe
#

A number is irrational if it cannot be represented as a ratio of two integers

#

One example is √2

mellow geyser
#

where the integers are coprime

fresh oriole
#

if x = A|B (this is Pugh’s notation of the cut A and B), and y = C|D, then:

x + y = E|F where

E = {r in Q | for some a in A and c in C, r = a + c}
F = the rest of Q

#

that’s the definition of a sum of cuts

serene vault
mellow geyser
serene vault
#

oh I'm not saying it's harmful in any way

mellow geyser
#

but then again, in the spirit of making as least assumptions as possible, maybe not having it is better

serene vault
#

it's just that usually it's not specified

#

unless coprimality is important in a context involving Q

idle steppe
#

Heres this funny proof of cube root of 2 being irrational. Suppose the cube root of two is rational. So 2^(1/3)=a/b where a and b are integers. And b≠0. Cubing both sides we get 2=a³/b³
So a³=2b³
a³=b³+b³. Do you see the contradiction?

mellow geyser
#

never seen the proof here, but isn't this fermat's last conjecture?

#

theorem, i guess.

idle steppe
#

Yeah, this contradicts fermat's last theorem

fresh oriole
#

using a hydrogen bomb to take out a mosquito bleakkekw

#

I wonder if there’s any hidden circularity in that

#

I really hope not

idle steppe
mellow geyser
idle steppe
#

Im NOT gonna look at the proof of fermat's last theorem

fresh oriole
#

haha yeah, no

#

there’s a very nice short proof that the nth root of m is irrational whenever m is not a perfect nth power of an integer

#

it relies on the fundamental theorem of arithmetic

#

you consider a rational number p/q and express the numerator and denominator uniquely factored into primes

#

and cancel any common factors

#

then consider raising it to the nth power

#

this just copies your primes, and no new cancellations are possible

mellow geyser
fresh oriole
#

so it can’t be an integer since there’s stuff in the bottom that doesnt cancel

fresh oriole
#

multiplication is a bit worse because you have to worry about signs

mellow geyser
fresh oriole
#

it should still

#

E should take the form (-infty, r) intersect Q

#

and then F is (r, infty) intersect Q

mellow geyser
#

and x + y is r

fresh oriole
#

where r = x+y

#

yup

mellow geyser
#

dedekind was gauss' student, right?

fresh oriole
#

good question, not sure

mellow geyser
#

I remember reading that on wikipedia

fresh oriole
#

apparently he was Gauss’ last student

mellow geyser
#

wow. Last was a blast

fresh oriole
#

no cap

mellow geyser
#

i will ask about the pi thing at the math village thing I will go to though. It still bothers me a little

#

i'm guessing we will discuss dedekind cuts since the name of the workshop is "real numbers"

#

or "Reel sayılar" in turkish

#

I think this is all my time (and maybe yours too) permits me to talk. I really enjoyed your company. I hope the conversation benefitted you, which it should. Of course it also benefitted me

fresh oriole
#

yeah, it was fun!

mellow geyser
#

I hope to see you around. I may come back later today or even another day

fresh oriole
#

I know what you mean about pi

mellow geyser
fresh oriole
#

I chat here a lot so I’m sure you’ll see me around

slender echo
fresh oriole
#

haha, wassup Tiny

#

what were we talking about last night…

#

oh, groups

#

that was good

slender echo
#

Yeah

#

I hope to learn abstract algebra eventually so that I can truly know groups

fresh oriole
#

you can do it! though I must say, having studied it a fair amount, I can’t say I truly know them

#

there’s a ridiculous amount of depth hidden in those axioms

#

but the more you learn the more interesting it gets

slender echo
#

That sounds cool

#

I’ll get there one day

fresh oriole
#

have you studied any set theory? just basics like unions, intersections, and how to notate them

slender echo
#

One of the chapters close to the end are about cardinality and ordinality,and/or counting if I remember correctly

fresh oriole
#

nice

#

you’re probably ready to start contemplating the definition of a group, then

slender echo
#

I look it up every now and then just to take a gander at higher mathematics

im using khan academy to prem myself for trig within 4 weeks, should i use something else or am i taking the right path?

hollow mist
#

Aight, ima ask something. I'm self studying linear algebra, and it's TOUGH. Everytime I feel like I understand something and feel like the concepts are getting easier and I can coast a little, the following concepts get harder and harder.

It constantly checks my progress speed, and every time I think I can speed up now that I get concept X, the textbook keeps giving new topics that stall me. It's hard to keep up with any reasonable completion schedule when this happens, and it's really demotivating.

Anyone have thoughts and opinions on this? Whether this is normal/How to speed it up/how to not be demotivated?

reposting here since #discussion was busy

rigid geyser
#

It's impossible to get to a spot where you just coast because then you rapidly move to a spot where you struggle

#

And while you're coasting you're not learning so that's a good thing

hollow mist
# rigid geyser And while you're coasting you're not learning so that's a good thing

I get it... but it's requiring all of my brain power from the absolute start. It's tiring, and I can't imagine that someone keeps doing this for 3-4 months for an entire course like this....

I guess I want to know if this is really that normal. I don't think I'm keeping ace with the recommended schedule of the course even because I'm having to explore so many practice problems to understand it completely lol

rigid geyser
#

What text are you using

#

Just curious

hollow mist
#

gilbert strang

#

intro to linear alg

#

strang is probably a little more numerical calculation focused

are you used to not struggling like in highschool level topics?

my preference would be a newer text by meckes/meckes designed for first course in LA for math majors (not eng). However that may or may not be better for you depending on whether a rigour focus helps you learn or not.

hollow mist
rigid geyser
#

possibly you are not used to not being throttled by the clss being slowed down for the pace to fit all students

#

you are probably also overestimatinhg how much the avg person who makes it thru a basic LA class understands all the material

#

but its immensely better for you to not be throttled

hollow mist
hollow mist
# rigid geyser but its immensely better for you to not be throttled

I guess I'm doing it slightly as a preparation for machine learning studies for bioinformatics, but I am also going to have to know some rigor since a lot of machine learning methods in new fields (like bioinformatics) require intensive proofs. You can't get any new methodology published or accepted without a reasonable amount of mathematical analysis, interpretability, and proofs.

#

so having rigor and the application related background is kinda... both important?

rigid geyser
#

personally i just returned from a long time away from mathematics (in industry) and am trying to self learn some stuff after forgetting like 90% of what i knew and its not uncommon for me to be stuck on a page for a day

hollow mist
#

(i am a bioinformatician by training)

hollow mist
#

Having the reference frame that this difficulty is normal gives me enough confidence to stick around for it.

rigid geyser
#

its especially true if youre trying to make sure you understand the material vs able to pass a test by memorizing some rules and blindly applying them the same way you did on the practice problems

hollow mist
rigid geyser
#

yep

hollow mist
#

AHHHHHHHHHHHHHHHHH

#

suks bolz

rigid geyser
#

a lot of these texts also have a ton of exercises with the assumption that the professor will choose which ones are good for the way theyu are teaching the material, which can suck if youre on your own

#

because its harder to choose yourself which ones should be done

hollow mist
#

Yeah... im doing all of them.

#

Ngl, doing all of them IS teaching me a LOT

rigid geyser
#

i looked at strang and there is like 70 per chapter

#

or something

hollow mist
#

but it's definintely slowing my pace down compared to what the avg uni student would do.

rigid geyser
#

thats also where a well varied amount of potentially more difficult exercises can be good (one of the reasons i recommend meckes/meckes over strang)

rigid geyser
#

doing 5 deep exercises could be more enligthening than doing 20 small ones

#

but yeah. doing all of them good. youll be doing way more than a normal student does though

#

there are some books that interspere the exercises with the text instead of the standard "end of chapter" which is sooo nice

hollow mist
#

That shit was sooooo abstract that each page was taking me 3 days

#

I have a copy of it from honors linalg from when I was in college

#

Ill try meckes

rigid geyser
#

doesnt hurt to have a secondary text to read up on concepts you are confused on anyhow

hi

pine glacier
#

can someone further explain why gojos limitless applies zenos paradox?

#

it is something im interested in explaining to other people

#

if someone could answer this, that would be great.
-thank you.

pine glacier
#

uh ok. doesnt really seem to answer my question

pine glacier
#

uhhh. doesnt seem to answer my question 🤔

#

Poor ants

#

can someone elaborate zenos paradox to gojos limitless technique??

#

i want to further my understanding and help explain it to other people

rocky shuttle
#

expand your domain

pine glacier
#

plss

#

someone answer

true zinc
sharp mulch
#

What sort of explanation to do you want

pine glacier
sharp mulch
#

It's a piece of fiction

pine glacier
#

zenos paradox

#

is not fiction

shrewd tree
#

Does anyone like Sam and Colby? And reading? (React with '❣️' if yes)

sharp mulch
#

Yes but gojo's domain expansion is fiction

pine glacier
#

im not talking about the domain bro. im talking about "limitless"

#

im sort of confused how zenos paradox applies to this and want to further my understanding on it

sharp mulch
#

Anyways

#

Based on some cursory searches online about gojo and whatever

#

So

#

Zeno's paradox is the idea that you can never reach a target because you can always subdivide the remaining distance into whatever right

#

It doesn't actually apply in reality because the shorter one of these remaining subsections is the shorter the time needed to traverse it

#

Blah blah blah convergent series

#

Jujutsu kaisen fandom site says ```Infinity (無限 Mugen?) is the base state of the Limitless and is essentially the power to stop.[4] The Limitless technique operates the same way convergent and divergent sequences do in mathematics. The Infinity is the convergence of an immeasurable series, anything that approaches the infinity slows down and never reaches the user.[5] This is because the technique takes the finite amount of space between the two subjects and divides it an infinite amount of times.[6]

In mathematics, no matter how many times someone divides a number it will never be reduced to zero. Instead, they will be left with fractional units so infinitesimal it would become immeasurable to their eye. The Limitless brings this concept into reality, so anything that attempts to penetrate this infinitely divided space will slow down to the point of appearing to stop completely.[7] ```

#

So if we want to say that this modifies reality so that zeno's paradox applies somehow

pine glacier
#

so you are saying that motion doesnt exist in that world which is why you said it is a piece of fiction

sharp mulch
#

One way to do it would be to have each remaining subsection of distance to be traversed take a fixed amount of time

raw horizon
sharp mulch
#

So like

pine glacier
#

in that way, it appears the projectile is stopped

sharp mulch
#

Let's say you can move with speed 1

#

And want to travel a distance of 1

#

Zeno's paradox would break this up into a distance of 0.9 and a distance of 0.09 and a distance of 0.009 and so on

pine glacier
#

it would be graphed as an ASYMPTOTE

sharp mulch
#

And traversing these would take 0.9 time and 0.09 time and 0.009 time and so on

#

But if you say that each subsection takes 1 time

#

Then the amount of time needed to get somewhere will be infinite

pine glacier
#

then if you had unlimited time to reach gojo, gojo would be the limit

#

i assume right?

#

also thanks for the explanation

Hello

#

do you have any math recomendations

#

how do you learn maths by yourselves

viral oracle
#

watching vids, reading books, doing exercises, and occasionally asking here

limber thunder
#

I'll repost smth I told another user this

cyan karma
lilac kite
#

tyyy All of this is practice, do any of you find ways to apply math before you learn it?

viral oracle
#

it can be helpful to understand where certain things apply I suppose, and there's usually a great job out there if you search "{topic} applications"

limber thunder
#

yeah I like reading about applications, though I kinda study in parallel to doing that

#

recently I was a TA for functional analysis and I also tried to focus in applications where possible

#

it appears in things like PDE, optimization

#

for more basic stuff like calc and ODE I also do try to relate that to concrete situations

#

books that aren't like, pure math oriented often have a ton of exercises inspired in application

lilac kite
#

how long have you been doing maths for do i have to have a lot of experience

viral oracle
#

a lot of experience to do what

lilac kite
#

master a topic of choice

viral oracle
#

depends on the topic and how fast you learn

limber thunder
#

everyone's at a different spot in learning, if you don't have a lot of "experience" you simply study the basics like calculus or maybe Book of Proof I linked above if you want to do proofs

personally I've been studying uni math for some years, currently first year PhD

viral oracle
#

I personally have decent experience with algebra and differential calculus, but only a few months into anything above calculus

limber thunder
lilac kite
#

integral and multivariable calculus

viral oracle
#

like, what do you envision you using math for?

lilac kite
#

physics

viral oracle
#

engineering? sciences? pure math? applied math?

#

ah

limber thunder
#

cool

lilac kite
#

so how should i learn it

#

how have you learnt math

viral oracle
#

where are you in your learning journey?

lilac kite
#

i dont know

viral oracle
#

as in, what math have you learnt?

limber thunder
# lilac kite how have you learnt math

I take my own notes based on books or lectures, then spend some time doing exercises from books, that's like the basic loop for each chapter lol

studying in groups or explaining things to other people also helps a lot, if you can proficiently explain a topic to someone else then you've mastered it

#

and math can be a very social activity even if ppl don't often imagine it as such

lilac kite
#

What lectures do you do

limber thunder
rocky shuttle
#

there's a math for physics course in my uni where you essentially cover all the topics relevant for physics (which are usually covered in a full undergrad math study programme) but crammed into a single semester and only at the surface level KEK

limber thunder
#

or in specific universities' pages like MIT Open CourseWare

limber thunder
viral oracle
#

I would say, Thomas over Stewart though

limber thunder
lilac kite
#

Woww tank yo so much i never knew about this

#

Thomas seems to provide a little more rigor from what I have seen so far (I do have both and work through both)

im convinced the former gifted kid stereotype "trying new things and quitting them when they don't come easily to you" is the result of former gifted kids trying new stuff at a higher rate and that mostly positive feedback at early stages in training is pretty much necessary and hard to find

#

First stage is for children which is an obvious difference but I don't think it changes much for adults. (also its talking about sport but i think the three stages apply to nonsport)

#

To understand my worldview better, I say if you're trying something new and have the choice between getting mostly positive feedback and getting real, harsh feedback, you would be better off getting mostly positive feedback until you have some level of competence where the "real" feedback is not too demotivating.

#

I'd love to hear other people's thoughts on this.

short acorn

That's nice

Saved

fervent hill
#

yeah it uses the fact that m1, n2, m2 and n2 are positive integers in multiple places

#

for example, it's used to say that m1 + n1 >= m2 + n2 + 1
and this is used to make a substitution in one of the steps

fervent hill
#

@short acorn there is intuition for it:
f is going down each diagonal from left to right. first (1,1), then the diagonal along y=3-x, then y=4-x, and so on.
now m+n is different for each diagonal. so if m1+n1 > m2+n2, then they should be on different diagonals.
then we should have f(m1,n1) > the rightmost point on the previous diagonal, which should be greater or equal to the right most point on (m2,n2)'s diagonal, which should be greater or equal to f(m2,n2).
and indeed following this reasoning, the algebra went through successfully

# tender idol How did u do the bicen maths videos

I created a list of chapters I wanted to master for the week, and then watched all of them in his playlists. After studying a chapter from his channel, I would try to find past paper questions on PMT to complete. If I struggled on a question, I'd just study that certain topic, not the entire chapter.

tender idol
#

Like tn it’s mainly some 3D vectors/planes

tough yoke
#

You've probably not studied them properly in depth and practise, if you're forgetting how to answer certain questions from a topic from time to time then that shows you haven't fully mastered the chapter. I suggest you restudy the chapter from his channel, create notes, then attempt some PMT and past paper questions.

@bold citrus okay so ‘solving’ a differential equation means finding the function(s) that satisfy the equation, that make it true

#

so for example let’s say some special system is modeled by the equation y’ = y

winged pawn
#

Picrew is where it's at

mint patio
#

‘solving’ that equation means finding the function y(t) such that its own derivative equals itself

#

can you think of a fnctn whose derivative is itself?

but we can actually do better

bold citrus
#

i was catching up haha but yeah e^x

viral yew
#

laplace goes crazy

mint patio
#

we can do better than e^x

#

take y = Ce^x, where C is a constant real number

#

when I differentiate the constant is unaffected, so my solution can actually be any function of the form Ce^x

#

e^x, 2e^x, … all work

#

differential equations model systems

#

a lot of the time, each term in a differential equation will actually correspond to some physical behavior of the system

bold citrus
bold citrus
#

thank you for your helP!

mint patio
#

we can solve differential equations to find a function which models the behavior of the system we were describing with our differential equation

#

for example, that motion equation I gave you describes … well, motion

bold citrus
mint patio
#

so the solution describes how the system moves

#

in this case ‘system’ is a specific particle

mint patio
#

but you know the great part?

#

a lot of systems are essentially parameterized by just a few variables

#

you can come up with a system of differential equations by describing the behavior of each of those variables (coming up with a differential equation with each variable in it)
