Riemann series theorem

In mathematics, the Riemann series theorem, also called the Riemann rearrangement theorem, named after 19th-century German mathematician Bernhard Riemann, says that if an infinite series of real numbers is conditionally convergent, then its terms can be arranged in a permutation so that the new series converges to an arbitrary real number, or di...

You guys know the portal question right

#

Moving portal contacts entity

#

Does the entity come out the other portal at some velocity dependent on the velocity of the portal? Or soes the entity come out of the other portal still at rest?

#

Which one do you think it is

loud snow Sep 17, 2023, 6:17 PM

#

def at rest

#

i dont think portals move

#

like if u think about it they instantly change positions of objects

why assume they can carry velocity

zealous garden Sep 17, 2023, 6:19 PM

#

If you think about it, it should fly out

loud snow Sep 17, 2023, 6:19 PM

#

the things that go into portals have velocity

#

portals themselves shouldnt

#

so anything that looks like moving is just instantly changing position in increments that looks like moving

#

ig its more right to say portals shouldnt have momentum

zealous garden Sep 17, 2023, 6:20 PM

#

Which means the portal is constantly being annihilated and recreated in its path of motion

#

Fine by me

loud snow Sep 17, 2023, 6:20 PM

#

nah i retract my statement

zealous garden Sep 17, 2023, 6:20 PM

#

Here's the thing

loud snow Sep 17, 2023, 6:20 PM

#

portals can have velocity

#

no momentum

zealous garden Sep 17, 2023, 6:21 PM

#

The portal displaces the first layer of atoms of the object to the stationary target portal

#

In order to displace the second layer, the first layer must be displaced

#

The rate at which the first layer is displaced depends on the velocity of the portal

#

This imparts velocity upon the object exiting the portal

#

This should also occur even to the air traveling through the moving portal

loud snow Sep 17, 2023, 6:22 PM

#

yeah

#

the velocity is coming from air though

#

air in location of second stationary portal

zealous garden Sep 17, 2023, 6:23 PM

#

How

#

I'd assume it's coming from whatever is maintaining the portal

loud snow Sep 17, 2023, 6:23 PM

#

portals like the ones in halflife sound inconvenient

#

i dont want to think about portals i just want to teleport

zealous garden Sep 17, 2023, 6:24 PM

#

In order to move the portal with a velocity, you would have to impart the energy necessary to displace the things traveling through the portal

#

So if you had a portal on a shield, using it to block something would feel exactly normal to you

#

Its just the thing you blocked would fall through instead of bouncing off

How doth a portal, port

In N dimensions, are portals all (N-1) dimensional?

#

That is their "surfaces"

Are their boundaries always (N-2)?

zealous garden If you think about it, it should fly out

Well yes since there is a relative velocity. It implies that the other portal isn't moving relative to the first portal though.

zealous garden Sep 17, 2023, 6:43 PM

Basically both portals need to be moving at the same velocity if you want the block to fly out.

Ah. Since the target portal is stationary, the block must be too.

zealous garden Sep 17, 2023, 6:48 PM

Why

sly flint Sep 17, 2023, 6:48 PM

#

I'm assuming stationary is said relative to something else other than the first portal.

zealous garden Sep 17, 2023, 6:49 PM

#

Yes, the second portal and object are both stationary to some third reference frame. The first portal is moving with respect to this

Dang it.

zealous garden Sep 17, 2023, 6:52 PM

#

From the first portals perspective, it receives an impact upon its surface (which means nothing really as far as the portal is concerned), and the object falls through it as expected.

From the other perspectives, the falling object is boosted by the portal

sly flint Sep 17, 2023, 6:52 PM

#

#chill message

zealous garden Sep 17, 2023, 6:52 PM

#

This makes sense, because the moving portal is rotated in spacetime

#

So it performs a rotation in spacetime, just like a Euclidean rotated portal would rotate like you'd expect

sly flint Sep 17, 2023, 6:54 PM

It shouldn't be boosted since the block as well as the portal are stationary with respect to the same reference.

#

I made a little thing, had to post it in chill.

zealous garden Sep 17, 2023, 6:57 PM

#

The portals can't reference eachother

#

They're the opposite sides of the same face

#

They're one thing

#

Properly, the dual space exists

sly flint Sep 17, 2023, 6:58 PM

#

zealous garden They're the opposite sides of the same face

Ah.

zealous garden Sep 17, 2023, 6:58 PM

#

The exit portal and entrance portal are inverse transformations

sly flint Sep 17, 2023, 6:58 PM

#

In that case it does make sense then.

zealous garden Sep 17, 2023, 6:58 PM

#

So the idea I have is

#

Take a manifold that is locally some flat portal, and pass another manifold through it

#

I suppose I can do this by integrating the associated transformation across the manifold

#

Anyways I'm not worried about all that right now

#

I mostly want to know if I can accommodate portals that are segments of (or complete) hyperplanes and hyperspheres

sly flint Sep 17, 2023, 7:03 PM

#

I'm not mathematically mature enough to understand all of it but that sounds nice. WanWan

#

Geometric Algebra

#

Then it just made sense

#

All you need is a mirror. Just imagine that you can go straight through the mirror into another space. And that's exactly it desu, another space. Not your original, the other side

#

Everything has flipped chirality

#

Moving on, compose those transformations

#

And you get classic portal action, translations and rotations

I'm ready

I'm going to need Pseudoriemannian Differential Geometry for this.

sonic field Sep 17, 2023, 7:45 PM

#

Take some 4 dimensional space. For the sake of consistency, we'll take minkowski spacetime within some localized coordinates. Let's assume that every point in this space carries measureables but exhibits no density so that they are 0 dimensional points. We wish to create a tunnel such that point a can travel through region R_a and R_b. Denote a curve C in this minkowski spacetime that is a riemannian surface. so it's smooth, and hausdorff, which is actually important. Take some points a* and b* to be the center of two clopen sets in our curve C. We'll look at this manifold from the top. We want to be able to "push" some point through these clopen subsets of C. For the sake of flashiness, let's create a boundary around these clopen sets so that there's polarized rotations sitting just outside of these clopen sets (these boundaries, are dimension M^(n-1)). We'll take another cylinder from another curve, call it C', and we'll use a gluing technique to roll it up into a cylinder. Or, we can cut some torus so that we only have half of our cylinder. The trick here is to roll up the curve C' in a way that'll 1. generate edges that are closed to "gently" attach to the bottom (or top if you will) of our curve C and 2. it must also be in some form of rotation itself. Since rotations admit additional measurables, it's appropriate that this C' be at least 2 dimensions higher than C. This is, what I would call, a pseudo-handlebody, or botched handlebody. From there, create equivalence relations to glue these two together (that actually probably wouldn't work, maybe direct sums so that this specific C' will be attached but will retain its higher dimension). Great, so now, our point mass/density whatever has a tunnel where it can travel through without having

#

To traverse the manifold it's sitting on. Next, you take a collection of worldsheets (for the sake of simplicity, let's just say worldlines) and union those together. What we get is a sychronized light cone (note hypersurface in whatever dimension), and that's not what we want. We want the space just outside the lightcone, since any particle (point mass/density w.e.) traveling outside a light cone is moving through spacetime faster than the speed of light. We wish to create a volume of of this spacetime (Call the lightcone LC and let the space be M^(n+2) or w/e and we get M^(n+2)\LC which gives us this space). Without going into those pen-rose diagram things, we end up with a double-triangular space that we can curl up. We curl this up using some creative equivalence relation, but the problem is that at the center of the point, we have the current present for every single pointmass in the universe. This might be OK. Anyway, if you can curl up that into a rotating torus with an infinite dimensional length and stick this into your C', you then have a point that can traverse time and move from point a to point b along those clopen sets in your curve C.

in the hyperreal number system you can have positive and negative infinitesimals which is essentially what 0 and -0 represent in floating point

Yep

At this point is it jusy anxiety that’s screwing with me or idk if I’m doing something wrong with my methodology

So, I mean to study a couple of books on mathematics (Serge Lang's Basic Mathematics right now) and get on to physics to aid my studies in music

#

I've got two questions, what books would I need to study after my planned Basic Mathematics and Hammack's Book of Proof to understand physics?

#

And is my an hour/hour and a half/sometimes two hours a day schedule going to get me anywhere?

#

I can hardly allocate any more time, without harming my other studies

#

do note that I took humanities all through high school, my exposure to maths and sciences is limited

#

my goal with mathematics is to have an understanding of calculus

Hmm, I'm not really sure. I think they usually include a few very difficult questions / very tricky questions in the multiple choice, and one very tricky part in the open ended

I remember when I took it we all got fucked over by some lagrange error bound question on the open ended

(im convinced that this is the only thing i got wrong... grrrrr)

because of this i held a grudge against lagrange error bound for years, but now i realize it's the best theorem in calc bc

Does anyone know why C++ code is usually like this

#


char result {};
bool failure {};
some_random_function(1,2,&result, &failure);
if(failure) { throw "Error"; }

#

They create variables then pass by reference instead of doing something like

(char result, bool failure) = some_random_function(1,2);
if(failure) { throw "Error"; }

surreal sapphire Sep 21, 2023, 6:13 PM

#

have you tried

#

functions cant return arrays

neat lintel Sep 21, 2023, 6:14 PM

#

hmmCat Why didn't they add it as a feature in the past

surreal sapphire Sep 21, 2023, 6:14 PM

#

arrays are quite complicated objects

#

arrays arent a real datatype, they are really pointers

#

and then you also need to store the length of the array to avoid memory issues

#

you can do that with a struct

#

oh actually i just read what you wrote actually opencry

#

i think the "correct" C way is to have some_random_function return an int

#

that constitutes the failure state

#

and then have result passed as a pointer like you did

#

so what you gave as example is probably just bad code

#

still you pass pointers a lot, because returning "arrays" is a hassle

#

and there is no datatype similar to Maybe that can encode failure states

trail sand Sep 21, 2023, 6:24 PM

#

You can do exceptions but yes this is largely an alternative to Maybe

#

If you're slightly insane you can simply return nullptr instead of a valid pointer for a failure

surreal sapphire Sep 21, 2023, 6:24 PM

#

this would require to return a pointer in the first place

#

its very common to just have every function return int (0 if it worked and something else to encode an error of some sort)

#

at least in my experience, though im mostly working with ancient code and also C, not C++

jagged forge Sep 21, 2023, 6:25 PM

#

I think C++ is supposed to have fancy semantics that lets you return data structures without actually moving anything

#

i believe it is called guaranteed copy elision

#

I don't really write much C++ or C but that code looks more C-esque to me

#

(even though it uses exceptions)

look at the stl

https://stackoverflow.com/questions/9857936/c-stl-containers-are-unusable-without-exceptions-what-can-we-do-about-this

Stack Overflow

C++ STL Containers are unusable without exceptions, what can we do ...

The supposed ethos of C++ is "what you use, you pay for". However, this can be quite debilitating due to exceptions and their pervasive use in the STL.

Before anybody says "just turn exceptions on",

on that stack overflow post

jagged forge Sep 21, 2023, 7:29 PM

its used in some projects

and not in others

pulsar pagoda Sep 21, 2023, 7:30 PM

jagged forge i agree, i am just objecting to saying outright that they are a "no-no"

the rule i have is the following. Is the project using exceptions and it has no conflicting dependencies with it? then exceptions are ok.

pulsar pagoda Sep 21, 2023, 7:32 PM

#

jagged forge what do you mean by "conflicting dependencies"

most projects handle errors with error codes

jagged forge Sep 21, 2023, 7:32 PM

#

that doesn't make sense though, you can mix and match libraries that do and don't use exceptions, the problem is when someone downstream you of wants to avoid exceptions, but you used exceptions in your project

pulsar pagoda Sep 21, 2023, 7:33 PM

#

it depends on your coding styld

#

style*

#

another thing with exceptions has to do with memory management

#

specifically the dump of the stack that is usual in most languages that require a runtime

#

like c#, java, python etc

#

the use of exceptions would hinder your capabilities for debugging memory errors too so there's that

#

https://isocpp.org/wiki/faq/exceptions

#

then again

#

im not saying u should not

#

but when ur considering it

#

go through the documentation to see if it fits

#

what you need

jagged forge Sep 21, 2023, 7:36 PM

#

yeah, there are reasons to prefer or not prefer exceptions, i don't really have a horse in this race. but i'm just pointing out i don't see a reason why you couldn't mix and match libraries in your application that do or don't use exceptions

#

the google style guide seems to ban them because existing code can't tolerate exceptions, but that's like, the reverse direction

pulsar pagoda Sep 21, 2023, 7:37 PM

#

jagged forge yeah, there are reasons to prefer or not prefer exceptions, i don't really have ...

code inconsistency

#

you would need to have good guidelines in your project to document the affected code too

#

also mind u im not saying DONT USE THEM

#

im saying you have to do this if your gonna use them

#

and you have to be explicit

jagged forge Sep 21, 2023, 7:39 PM

pulsar pagoda Sep 21, 2023, 7:49 PM

bitch, you have a bunch of files that compile to javascript from a compiler written in js, to keep your generated js in memory (assuming your not compiling the files). And even then its bad because you have to do IO calls which is the pain point of node

#

also bun has good things though

#

they build the typescript interpreter directly into the runtime and its written in zig

#

mind u i dont know about zig

#

but that to me sounds better than whats done in node at the moment

that's more just a property of the language design tho, and not the parts related to IO

pulsar pagoda Sep 21, 2023, 7:52 PM

but the moment you need to deal with state coming from a file thats outside of a promise or event

jagged forge Sep 21, 2023, 7:52 PM

try doing that with thousands or 100 of files

#

youll get a seg fault

#

only way to do that in node is to have it deal with single instances and make it scale using containers and k8s

#

at least thats how a senior

#

did it

#

in a place i worked

jagged forge Sep 21, 2023, 7:53 PM

100 or 1000 files is not even that much

pulsar pagoda Sep 21, 2023, 7:53 PM

well i worked at a place with a service that handled 500million files monthly

their application crashed if you tried to input more than 4000 files

#

mind u some files were and average of 10mb

jagged forge Sep 21, 2023, 7:54 PM

#

right, well there's no reason to keep every file in memory all the time

#

just keep a hold of the file handles and store offsets into the files when you need them

pulsar pagoda Sep 21, 2023, 7:54 PM

#

what happens if there is a file that is referencing information from a different file?

jagged forge Sep 21, 2023, 7:55 PM

then swap stuff in and out of memory as needed
