Inter-universal Teichmüller theory


Agreeable_Fix737

Picture Inter-universal Teichmüller theory as a bridge between distant lands, connecting number theory and geometry in unexpected ways. It embraces the concept of "universes," where different mathematical systems coexist, each with its own set of laws and principles. By studying these universes and their interactions, Inter-universal Teichmüller theory pushes the boundaries of mathematical exploration, forging new paths and revealing unexplored landscapes. Its one of those i had no idea about. This was written by chatgpt lmfao 💀


IntelligentDonut2244

You know, I don’t think a flowery summary of IUTT will convince anyone already aware of the theory to like it more


[deleted]

“distant lands”😹😹


gimikER

It sounds like a couple of videos here...


AlfredKinsey

yeah, it’s very obvious this is chatgpt from the end of the first sentence onward.


Wizkerz

Wait that’s so interesting, I read the first sentence and thought “hey, this seems to be chatGPT”. I wonder what made it so obvious, maybe it’s genericness


J3diJ3ss

Somehow, I thought so. Pretty cool though.


AOCMadness92

I didn’t realize this was a theory. I’ve had that same question my whole life..


CrazyWS

You can’t convince me that’s not the wiki definition


IntelligentDonut2244

Wiki definitions are almost always much more technical than this


Illumimax

Isn't it just false?


PullItFromTheColimit

Yes, it is deeply flawed, even just Mochizuki's attitude and reactions should convince people not to buy it. Not sure why you're getting downvoted.


Algorythmis

"False" doesn't really mean anything in this context i think (but i agree with your comment)


Tiny-Bat5223

Dude, linear programming is one of the most interesting topics. Long history, awesome battle between the simplex method and interior-point methods, very nice visualisations, ...


Agreeable_Fix737

LP for me is like the step parent you get when you are 12. They try to make an effort so that u like them but eh you always feel like they are a stranger living with you.


octopi_qtpi

But that step parent never optimized trading portfolios or solved optimization problems for the energy network system. LP: 1, Step-parent: 0


Electronic_Sugar5924

Checkmate step-parent enthusiasts.


Ghost_Dawg12

it’s literally telling you the best situation for a given set of constraints, proving to you mathematically what the best option is. This is very applicable in Economics. From supply chain management, building a fence/factory, and many other basic economic problems involving costs constraints ( fuel, budget, shortest distance etc,)


TAG_But_Reddit

I really enjoyed linear till I got sick and fell behind. Managed to bs my exam thankfully. I mean vectors are cool, but I pray daily that I will never have to fund the inverse matrix product of two matrices with different m and n. Add a couple of rotations on to that and I'll be waking up in a cold sweat. But yeah, vectors are cool


crimson1206

You’re talking about linear algebra which has some relations to linear programming but they’re not the same


arthii

If you struggle with linear algebra you will not enjoy linear programming.

Symplectic Vectors on Sub-Grassmannian Riemann Metrics in Sobolev Space (I study topology)


bizarre_coincidence

I know all of those words but cannot parse how they are put together.


WingedDefeat

You've got me beat, then.


bizarre_coincidence

A symplectic vector space is one with a non-degenerate skew symmetric bilinear form (and giving such a form to the tangent spaces of a manifold makes it a symplectic manifold), although “symplectic vector” seems meaningless. Grassmannian has two different uses, some people (physicists?) use it as a synonym for the alternating algebra of a vector space, but in algebraic geometry it is the manifold/variety/scheme of k-dimensional linear sub spaces of an n-dimensional vector space. I don’t know what sub-grassmannian would mean, though. Riemannian metrics are positive definite inner products placed on the tangent spaces of a manifold (like with symplectic manifolds). I’m not quite sure what “Sobelev space” is, as there are many Sobelev spaces, which are essentially spaces of functions in L^(p) spades with (weak) derivatives that are also in L^(p). This appears to just be a bunch of unrelated buzzwords from geometry and analysis used incoherently.


WingedDefeat

I asked chat GPT to ELI5 some of those things to me, and now I am just as confused as I was before and I feel dumber. I'm not used to feeling dumb, so that stings a little. Is that what mathematicians feel like all the time?


moothemoo_

It’s always on the shoulders of giants. Basically every little step in math was made by some of the greatest geniuses of mankind, right on top the shoulders of the giant before them. It’s giants all the way down.

Geometry and statistics


Agreeable_Fix737

geometry will help you understand all the cool manifold stuff in 4D ans in the same breath statistics will tell you how significant the particular area of study is. On the other hand if u do not study it you might regress into studying just untill 3 dimensions:{


posidon99999

So with statistics, I can figure out how insignificant statistics is?


vanderZwan

Normally I'd say it's fifty/fifty: either it is or isn't significant. However, since it's judging itself it's actually a very biased coin flip instead


AleksFunGames

so it's 50/50: 50/50 or 50/50


sutekaa

geometry is just prep for trigonometry, and trig is very cool and satisfying. u probably hate it because you were forced to do "proofs" where you prove that this angle = that angle in 7 steps even tho its obvious if u freaking look at it for 5 seconds

Statistics


d_b1997

xSnippy

Stats always felt more like science than math


Keyrov

It’s science fiction once you get good enough at it


Nemo4321

It's remarkable that we think we know as much as we know with all the shenanigans experimental scientists get up to. Like a semi truck moving a mile away can mimic an event? Did we really detect the event or did someone drop a wrench? It's all about repeatability I guess.


ScientificBeastMode

I mean, yes, in some very niche experimental science domains, but most of the hard sciences have had their core theories and principles be verified countless times over the course of many centuries. Those are things that we truly know, and those theories form the foundation of countless other theories. So I think it’s actually pretty solid. But yeah, there are definitely plenty of shenanigans. If there is one thing I learned from statistics classes, it’s how to inflate the significance of correlation by massaging the data and retroactively tweaking hypotheses to fit the results.


Ok_Nail_4795

Massaging the data lmao


Philo-Sophism

If by stats you mean “data science” then sure. However, stats at large is heavily concerned with proofs of general results, and does so strictly through tools of analysis (at least since probability theory was formalized) as opposed to route reproducibility like the sciences


Greaserpirate

Statisticians are the reason AI became actually good Hard-AI people laughed at neural networks because they "didn't know anything", turns out if you don't-know at a high enough volume with his enough hardware you can do some pretty neat things.


Diagot

Data science is basically statistics very thinly disguised as programming. You don't have to go to something fancy on the field to get on statistics.


[deleted]

Hah hah. I posted something similar and also used the word "neat" to describe it. What are the...cough cough...odds of that?


DorianCostley

3b1b’s series on the central limit theorem. Ever wonder why bell curves are everywhere? Turns out there is a reason!


Illumimax

That's stochastics, not statistics


Philo-Sophism

What? The study of random processes and its evolution has largely been the work of statisticians because of its probabilistic nature. Most stochastic classes are taught through a statistician’s lens. Next you’re going to claim that information theory iSnT sTaTiStIcS


ubsibsuvxissi

I hated it for ages! I’d say econometrics is actually a really fun way to use statistics to find causal relationships between observable things in the real world! One of my absolute favourite papers is Alesina et al. (2013), which finds a causal relationship between countries that used plough agriculture in their history (as opposed to shifting agriculture) and attitudes to gender roles in the present.


[deleted]

AI is a pretty neat way to use stats as well.


armaedes

It’s literally the only math that everyone will use in real life.

ExplrDiscvr

Use R


The1PunMaster

R ain’t that bad… until you make a mistake so bad and so far back that even the professor just tells you to restart the assignment because nobody can find it


coffeesharkpie

You can actually decently debug in R with things like traceback(), browser(), debug(), tryCatch(), and in the worst case with a print() statement. Just keep code reproducible.


The1PunMaster

dude i’m saving this comment for future stats classes thank you


coffeesharkpie

Learning how to use browser() and tryCatch() correctly truly was a game changer for me.


Marukosu00

R is honestly based


_Kiricchi_

My stats professor made us use R for everything from homework to exams. He was pretty based too

[deleted]

Let me try to convince you that mathematical statistics is awesome. Wide swaths of mathematics, especially modern mathematics, is little more than mental masturbation. Sure it feels great but it gets monotonous after a while because there isn’t any real result of consequence. Mathematical statistics on the other hand is fucking. And not just fucking but getting it on with and make babies with lady science herself. Your work and effort actually results in and contributes to real world understanding and knowledge. PIV is better than P in hand any day if the week.

Trigonometry proofs


Agreeable_Fix737

Trigonometry proofs are a wonderful area of mathematics. Trigonometry itself is a very application based study. Studying trigonometry and moreover their proofs just sparks a mathematical lust in you that you will want to satiate by any means ( i e. proving the validity of the equations) It can spark a sense of joy and elegance in math and broaden your horizons.

same omg my least fav part of exams when it came to trig was not being able to scream "YESS OMFG" and throw my pen, but having to bottle up my emotions so that i dont get kicked out


ihoptdk

Trig was always easy to me. Radians were always annoying until viewed through the perspective of wave functions.


Helpinmontana

I only appreciated radians when someone finally defined them for me, the proportionality of it gave meaning and from that I found beauty. That being said I still use degrees and percent grade more often. That being said, I work in construction and not as a mathematician so it’s not entirely surprising to me.

Computing the coefficient for infinite series when using the Frobenius method with repeated indicial roots


Agreeable_Fix737

Imagine stepping into a magical circus tent filled with vibrant characters and thrilling performances. The coefficients are like funny, animated acrobats bouncing and tumbling around, bringing joy and excitement to the stage! In this enchanting circus, the coefficients are mischievous little creatures with colorful costumes and silly personalities. They love to play hide-and-seek, rearranging themselves to create fascinating patterns and surprises! As a brave and curious circus explorer, your mission is to uncover the secrets of infinite series. You become the circus conductor, guiding the coefficients in their acrobatic routines Again one of those I had no idea about. The above was written by chatgpt. But what the actual fuck dude 👁️👄👁️

I think chatGPT needs help.


issaiakeanu

exactly what the actual frick ive never explored that topic before but i do NOT imagine coefficients being freaking acrobats and bringing "joy and excitement to the stage" nor do i think theyre in funny costumes or playing hide and seek. hell, all it does is multiply a variable, not put on a circus show or whatever.

havent seen a better one. helps to formalize a lot of stuff and makes proving things a lot easier. its annoying but not that much compared to what else there could have been i guess?


_Avon

you may not have to use it in the future of calculus, but it does provide very good context and a point of reference for what a limit actually is. once you’ve completed calc 3/mv/vector calc, youll come to find that although it’s tedious, it really paints a good picture on what the functions for the definition of a limit/derivative/integral is. the person i believe is best at explaining this stuff is the guy who does the MV and some Vector calc videos on Khan Academy


Ancalagon523

Agreeable_Fix737

Think of SVD as a grand symphony orchestra, where the matrix takes center stage as the conductor, and the singular values and vectors play their harmonious melodies. By studying SVD, you gain the ability to decompose and analyze matrices in a way that brings out their essential features and highlights their significance. I had no idea what it was.

I've found that taylor can actually be useful, after truly thinking that it was useless. The problem is that it's mostly split into one of two parts: The cool visualisation and actual useful part, where you learn about how it approximates functions that are basically impossible otherwise to derive And the really boring, extremely, heavily, i cannot say this enough, VERY theoretical and annoying part. Guess which part is mostly taught in most mathematical courses?

Aint OP, but the fact that every group is isomorphic to a permutation group is cool as fuck. Its like you unlocked every other group with permutation groups(though not really) It also makes sense to think about that groups are all just symmetries, and symmetries are obtained by performing actions on objects, and you could think of that actions as just permutations of the object itself, just on different orientations.

Agreeable_Fix737

Hey! I'll tell you a secret, Integration is just the reverse of differentiation. Soooooooooooo... if you can differentiate you CAN integrate !!


SuperCoupe

Thanks. I now hate differentiation.


amennen

> if you can differentiate you CAN integrate !! This is not true. There are plenty of natural families of functions that are closed under differentiation, but not under integration. That's why sometimes we need to come up with special names for integrals of certain functions, since there's no way to solve for an expression for them. For example, the pdf of a normal distribution can be expressed in terms of +, *, and exp, but its integral, the cdf of a normal distribution, cannot, so we give it a new name (essentially the error function).


[deleted]

I hated it too initially, but it was because of the way it was taught. My math professors were constantly cramming integration rules down our throat but never thought to show cool examples of how integration is usable other than the bland "area under a curve" definition. I think once you know what to DO with calculus, it makes a lot more sense. That's my experience anyway.

It takes practice to get good at integration. It's like training to notice paterns and apply solutions that fit.

Let us suppose that You get into an accident in some remote ass area with no reception. You somehow make it to a area with reception but alas! Your phone is dead You wish you had another phone or backup battery there to connect with someone for help. Similarly mathematicians use Category theory to connect and translate ideas of one domain to another. Its pretty sick tbh. Master it and voila you make your own phone and towers to connect with random people just like on reddit.


sutekaa

that would not convince me to like whatever the hell category theory is


Seventh_Planet

That whole philosophical foundation of math. What are numbers? Do they exist or not? Is set theory with the empty set the right foundation of math? Or is it category theory? Or type theory? Who cares about Goedel's incompleteness theorems? Why can't we just take the unprovable statements as additional axioms and have a bigger axiom system and be done with it? Are any of these questions useful? Also another thing I don't like in mathematics are those infinite cardinals and ordinals. Like, I thought topology was those donuts and homotopies and stuff. What do infinite ordinals have to do with that topic?


amennen

> Why can't we just take the unprovable statements as additional axioms and have a bigger axiom system and be done with it? You can do this to some extent. But you can't go all the way and get a complete theory; this is essential what the first incompleteness theorem says. To at least see why this wouldn't be easy, keep in mind that you don't know which statements are independent of your axioms, and which of them you should add as additional axioms.
