Welcome to the server @grim yacht

[atomic seal]

@cold forge affine variaties are cool 🙂

took some time to get wrap my head around all the sheaves stuff

[cold forge]

they are cool!

[cold forge]

yeah like honestly they should be taught in elementary school

[atomic seal]

real

[cold forge]

just like category theory

thats the important stuff

[atomic seal]

tbh if math was taught at a faster pace (and not 12 years to get to basic calculus) it is very possible to reach advanced things

[atomic seal]

I will need some help with cat theory xD

I think Milne just assumes that everyone who reads his AG notes knows cat theory

[cold forge]

it is good to be familiar with universal properties and limits and colimits

[atomic seal]

yep I can see that

when the definition of a stalk is basically a colimit

[junior veldt]

could you actually do this

[vivid halo]

lol no

[cold forge]

and when you have the intuition of colimits it really just makes sense that it works this way

[junior veldt]

hi nG

[vivid halo]

howdy

[junior veldt]

hru doing

[atomic seal]

what summoned you two?

"cat theory"?

[cold forge]

category theory probably

[junior veldt]

ig so

[vivid halo]

not great! but better than the last few days I guess

[junior veldt]

hope you feel even better soon

[cold forge]

dont we all..

[vivid halo]

yeah I feel mostly better now guh

[atomic seal]

what intuiton are you talking about?

[vivid halo]

had horrible horrible lack of sleep earlier in the week and then made up for it by bedrotting for a few days

then had pretty bad migraine yesterday

but doing okay today

feeling very disorganized with the preprints I'm trying to finish guh

[junior veldt]

oh i got my first preprint recently

[cold forge]

well the stalk of x can be thought of as the set of functions of the sheaf defined on some neighborhood of x, where two functions are identified whenever they agree locally at x, that is, on some neighborhood of x.
this is exactly what a direct limit does

[atomic seal]

that was the definition

[junior veldt]

well that's the construction of a colimit, at least

though not really its universal property

[cold forge]

oo whats it about

[vivid halo]

it's still wild to me that you can do reasonable geometry with prestacks (no gluing conditions whatsoever, just functors)

[junior veldt]

some stuff i did in my undergrad about bootstrapping QM

[vivid halo]

oh nice

[cold forge]

no but that behavior is the intuition to have for direct limits

[junior veldt]

ig i like the intuition from coends

since they provide a "polymorphic" version of $\exists$

[fathom swallow]

Pseudo (Cat theory #1 Fan)

[junior veldt]

which is essentially what you want - there exists an open neighbourhood of x with a function defined on that neighbourhood

[cold forge]

yeah

[junior veldt]

the identification is just built into the categorical def of "there exists"

you're basically doing $\int^{x \in U} F(U)$ after all

[fathom swallow]

Pseudo (Cat theory #1 Fan)

[junior veldt]

which you can read as $\exists x \in U . F(U)$

[fathom swallow]

Pseudo (Cat theory #1 Fan)

[cold forge]

gotta be honest i know basically nothing about coends

[vivid halo]

lol yeah I also never properly learned coends

[junior veldt]

to me they're a really pretty idea

[vivid halo]

yeah they are quite nice

[cold forge]

only thing i know is "category theory integral"

lmao

[junior veldt]

ends and coends provide categorifications of $\forall$ and $\exists$

[fathom swallow]

Pseudo (Cat theory #1 Fan)

[junior veldt]

but with naturality built-in

[vivid halo]

they just don't come up often enough for me to remember a lot of the details around them

other than like, Day convolution as a special case

[junior veldt]

there are lots of categorical definitions that can be written as "forall blah, a morphism from foo to bar such that this diagram commutes"

ends let you just read the "forall" part of that statement and write it as an end

the naturality follows automatically from the definition of the end

[vivid halo]

yes this is what depedent products/dependent coproducts are for, and I guess you can write these in terms of ends/coends

[junior veldt]

mhm

they also appeared in yoneda's phd thesis

so they've been around for a very long time

[vivid halo]

I have got a lot of mileage out of this dictionary for representation theory

[junior veldt]

interesting

i actually know more about the HoTT side of this table than the rep theory side

[vivid halo]

it's neat how (co)induced representations can be viewed as dependent (co)products like this

[junior veldt]

that is quite cool

[vivid halo]

and that this gives you all the adjunction properties for free

[junior veldt]

yeah i guess the nice thing about classifying spaces is that they let you view representations in a "fibred" way

so you can apply all these techniques from dependent type theory

[vivid halo]

this is very similar (identical in content) to how people these days think about representation theory in terms of 6-functor formalism

[atomic seal]

do you guys know etale cohomology? how much prerequisites are there for it?

[junior veldt]

as opposed to viewing them in an "indexed" way with a functor out of BG

[vivid halo]

yes I know lots about this

[junior veldt]

i know nothing about this

[vivid halo]

the prereq is basically AG at the level of Hartshorne (chapters 2 and 3 especially)

like as long as you are comfortable with schemes and sheaf cohomology

etale cohomology is usually the first time you learn how to deal with sheaf cohomology for more general sites rather than for topological spaces

[junior veldt]

oh interesting

[vivid halo]

understanding some of the content about curves from Hartshorne chapter 4 is useful especially once you get around to the first real computations of etale cohomology for curves

[atomic seal]

ok so I have a lot to learn

[vivid halo]

yeah haha

[atomic seal]

actually there is a class on sheaf cohomology starting soon in my uni

I will try to get notes from there

[vivid halo]

nice nice

[junior veldt]

i've heard some stuff about sheaf cohomology

measuring the failure of local solutions to glue to a global one?

[vivid halo]

my previous advisor taught a really nice course on etale cohomology and the Weil conjectures you can find all the recordings here https://www.daniellitt.com/tale-cohomology

[vivid halo]

yeah typically this is defined in terms of derived functors of global sections

[junior veldt]

interesting

so it's a notion from abelian categories?

[vivid halo]

if you're dealing with sheaves of Abelian groups or modules or whatever yeah

[junior veldt]

mhm

[vivid halo]

if you have a sheaf of Abelian groups A on a space X then H^0(X,A) is global sections

[junior veldt]

oh ok

is that just A(X)

[vivid halo]

yeah

if you have a short exact sequence of sheaves of Abelian groups 0->A_1->A_2->A_3->0 on a space X then global sections doesn't preserve this exact sequence

[junior veldt]

mhm

[atomic seal]

so I need AG up to sheaf cohomology

but I really have no experience with homology/cohomology

its from alg top right?

[vivid halo]

you get 0->H^0(X,A_1)->H^0(X,A_2)->H^0(X,A_3) but not 0->H^0(X,A_1)->H^0(X,A_2)->H^0(X,A_3)->0 in general

[junior veldt]

hm why does the last part fail

[vivid halo]

well the failure is measured by H^1(X,A_1)

[junior veldt]

oh i mean more conceptually like

why would i expect the last part to fail

[vivid halo]

in general you get a long exact sequence
0->H^0(X,A_1)->H^0(X,A_2)->H^0(X,A_3)->H^1(X,A_1)->H^1(X,A_2)->H^1(X,A_3)->H^2(X,A_1)...

[junior veldt]

it's a failure of surjectivity of the map X(A_2) -> X(A_3) right

uh wait

[vivid halo]

oh it's what you said before, namely obstructions to gluing local sections to global sections

[junior veldt]

A_2(X) -> A_3(X)

hm...

i guess i'd need to work through a concrete example to see this#

but i can black-box it for now

[vivid halo]

usually the motivating example is the complex logarithm on C-{0}

[junior veldt]

is it weird this reminds me of mayer-vietoris

[vivid halo]

you can always find local sections for the logarithm, but you run into issues gluing these to a global section because of monodromy

[vivid halo]

not at all, they come from the same idea

[junior veldt]

ok gotcha

[junior veldt]

ah sure sure

i guess my issue with not knowing the formalism is that sheaves are all about "gluing compatible local sections to a global one"

so a priori it's not obvious to me what is actually meant by "failure of local sections gluing to a global one"

[vivid halo]

yeah I guess the main point is that sheaf cohomology is what is actually measuring this failure

like classes in H^1(X,A_1) are obstructions to this sort of local to global construction for global sections

[junior veldt]

i see

[vivid halo]

same can be said in higher degrees

[junior veldt]

so it's somehow measuring the inability to choose a bunch of compatible local sections?

[vivid halo]

yeah

[junior veldt]

fascinating

[vivid halo]

like in the logarithm example, you have a nontrivial obstruction coming from monodromy around 0

and that really does see some nontrivial topological fact about C-{0}, that it is not simply connected

[junior veldt]

honestly i feel like this makes "homology is indicator functions for algebraic structures" make even more sense to me

[vivid halo]

when you apply sheaf cohomology to very specific kinds of sheaves (locally constant sheaves) then this recovers the usual constructions of singular (co)homology

but it applies to other kinds of sheaves as well

it also applies to sheaves defined not just on topological spaces, but defined on more general Grothendieck topologies

[junior veldt]

yeah that makes sense

i guess the main thing is trying to find an analog of the "global sections" functor?

on a more generic site

[vivid halo]

sure

[junior veldt]

my initial guess would be $\int_U F(U)$ or something

[fathom swallow]

Pseudo (Cat theory #1 Fan)

[vivid halo]

well usually it's like

[junior veldt]

where U ranges over the objects in your site

but mb not

[vivid halo]

global sections is usually just coming from a terminal object

[junior veldt]

right, which the end would recover

but what if your site doesn't have a terminal object?

or do i not need to worry about that

[vivid halo]

I can't think of so many examples where one has to worry about this haha

[junior veldt]

ok cool

i'll keep the end def in mind then

[vivid halo]

like for etale cohomology the site in question is the "small etale site" of a scheme X

objects of that site are etale morphisms of schemes Y->X

morphisms are commutative triangles as one would have in a slice category

[junior veldt]

mhm

[vivid halo]

terminal object is the identity X->X

[junior veldt]

makes sense

[glossy sparrow]

i have a doubt

[vivid halo]

in almost any reasonable example I can think of you're always dealing with some category with a distinguished collection of "covering families" including the terminal object and closed under pullback

the etale topology is finer than the usual Zariski topology

Zariski covering families are etale covering families but you have more etale covering families which are not Zariski covering families

the closest analog in the setting of smooth manifolds would be the local diffeomorphism site

[junior veldt]

-# idk what etale covers are @.@

[vivid halo]

that's fine it's not so relevant

you can think of etale morphisms of schemes as similar to local diffeomorphisms of smooth manifolds

@vivid halo this is the syllabus for that course

does this sound good to you?

[junior veldt]

mhm

[vivid halo]

this is decent as a preparation for etale cohomology yeah

[atomic seal]

Thanks

Its starts in a month or so

so I have some time to prepare

[cold forge]

ooo the book by Bosch is beautiful

as in like aesthetically pretty

[atomic seal]

good to know

But I will stick to milne for now

I am slowly learning names of authors

[latent edge]

The cover?

[cold forge]

no like the whole book

idk why

[latent edge]

I haven't tried it

[cold forge]

it has some nice pictures too

[latent edge]

I learned yesterday (and will continue today) how Galois groups correspond to deck transformations

Last time I stopped at taking 2 copies of C and doing some quirky branching stuff to make sense of field automorphisms

[cold forge]

thats related to the fundamental group of an affine scheme right

[latent edge]

yea etale fundamental groups

[cold forge]

everything is etale..

everywhere i go i see its name

[latent edge]

It's neat stuff

Not sure why I was scared before

[cold forge]

whats the overarching idea of "etale" stuff

Yes, please do you have any pre algebra book recommendations?(for a beginner)

[reef carbon]

no

you might have better luck in#book-recommendations

but if you really wanted to grab my attention you... could have simply said one message

[kindred trellis]

My bad🙏

[reef carbon]

like, saying just this:

@Ann hi, do you have any pre-algebra book recs for a beginner?

this footnote (10) is wild

euler did formal power series and exponentiation on the algebraic structure known as the wheel?

[vast wraith]

idk here’s the reference for the extract from euler if you want to contextualize it:

this (excellent) book btw is luboš nový’s origins of modern algebra

[vernal token]

Jens are you studying mathematical history? You always post historical stuff and I never asked

[vast wraith]

um well i spend quite some time reading math history

maybe i should look into whether i could try study it officially

but idk if i actually want that

[long patrol]

Fuckkkkkkkkkthis life

[night garden]

i haven't been revising my stuff for all of my summer holidays and forgot all 7 modules
I have abstract algebra lectures tomorrow would u recommend learning the stuff i forgot like calc 1 and 2, probability statistics 1 etc or should i only re learn Linear algebra?

Would u say its a waste of time to re learn my other modules i dont have enough time for the others so im wondering if only re learning linear algebra is fine

(ik this is discussion and less math focused but i need helpppppppp) 😭😭😭

[vast wraith]

like, doing a masters in math history might be possible

[night garden]

Some1 help me out 🥹

[long patrol]

What do you think¿

[icy heron]

Euler would be a frequent flyer in #crank-discussion if he were alive today

[vivid quest]

I do want to learn a bit about math history

Do you have a book recommendation?

[fresh comet]

[vast wraith]

well what sorts of maths are you interested in ?

[neat lintel]

I wouldn't imagine you'd need any of that for abs alg lectures, linear algebra might be good cause you may be able to draw parallels but if this is your first brush with abs alg then it's fine to go without prior knowledge (learning how to frame proofs however will help, which you'd learn in this course anyways)

[vivid quest]

Im not knowledgeable at all in math history, i just wanna start somewhere to see a bit of everything and then see what part im the most interested it

Or maybe not a book but something else

A podcast or a video would do too for a start

[neat lintel]

Abel died of tubercolosis when he hit his 30s just a few days before getting a univeristy position

almost all of my math history comes from like textbooks which have those little boxes mentioning the mathematicians/scientists 😭

I was reading this abs alg text and there was section on lagrange and abel, very cool

a lot of it is surprisingly tragic though

He died when he was 26 nevermind

[pseudo lotus]

...

[night garden]

Thank you, ill try what you said because no way do i have enough time to re learn 7 whole modules 😭

• new ones

[neat lintel]

yeah but don't forget to spend some time everyday revising all of that cause the courses up ahead might require some preliminary knowledge/preliminary knowledge will help

[night garden]

[lavish kayak]

it's cool it's completely normal to forget most of the material, it's a sign for you to review your study methods and to know what material was more important.

anyhow, there's not much review you can do to prepare for abstract algebra, it's a completely new subject. You can skim the textbook if you want.

[night garden]

Ohh ok i just thought abstract alg would be a continuation from linear alg

Guess not

[old oak]

Have you seen #discussion ?!

[toxic python]

yes i have

quite a lot going on at the same time

[old oak]

Precisely, and some of us like a more sedate experience

[toxic python]

same

[lofty forge]

But wait, what stops them from coming here and pretty much making this place twitter too, like they can come here at any time, so why don't they, maybe some insane psychology is at work

[burnt ledge]

nothing stops them

nevertheless they don't

[merry plank]

Oh so you say I should positively influence discussion two too?

[shy summit]

Hii

[tame egret]

[neat lintel]

It's just not active enough for them to actually get in on it, plus this place usually has more thought out conversations which discourages most people

[lofty forge]

Yeah true, the lack of activity is what stops them IG

[neat lintel]

the contrast is nice though, cause it's essentially made this channel a sort of safe haven cause literally everyone is up there discussion so you can actually talk about things more productively here
I think discussion will remain like the dumpster fire it is because now it's sort of engraved that whatever's happening up there right now is the norm, no matter what measures are taken

the off topic channel in the physics server however feels more tightknit and under control (might be because they ban at sight), not that it doesn't have it's weird moments but it isn't as active and jumpy as discussion
I think it's also cause most people get a little intimidated because like there's actual on topic convos happening

that being said discussion is fine but there's just a little bit of entropy that makes it uncomfortable

[fresh comet]

I like both channels

#discussion for its chaos, and #serious-discussion for its calm :p

we gotta have a bit of both in life sometimes

Doing some leetcode to try to get slightly less rusty at coding, wrote a solution I felt proud of, used a stack and hashmap and all of that good DSA nonsense

35% for time and memory

[dark stone]

why leetcode?;3
wanna get a job in coding?

[glass peak]

Possibly, I’ve been talking with some quant people and I have a coding test coming up and I’ve basically not done any for 2 years lol

I think I’m still probably going to go for academia but I’ll give it a bash

[cinder zephyr]

do not pay attention to the %s lmfao

exceptionally useless

just make sure your big O time and space are optimal (often there is a tradeoff, understand these)

the %s vary widely depending on how warm the testbench is, cache optimizations, language, etc

[burnt ledge]

sometimes when im bored i farm for best % by js running the same solution over and over again

theres a very large variation

[glass peak]

That is actually true I ran it a few times and did manage to get 100% one of the time, and I guess that makes sense when we’re talking about code running in like single digit milliseconds

[glass peak]

This is actually one thing I don’t really understand, I’ve never taken CS coding courses and none of my scientific programming courses ever cared about writing good code, I really have no idea how you’re supposed to balance memory and time complexity

I’m guessing it’s very much a “it depends” based on the problem and use case but yeah

I can pretty much work out time complexity too but I’ve really got no idea about space complexity

[burnt ledge]

if youre populating a list that isnt your output chances are youve got linear space complexity

otherwise youre probably constant space complexity

Ts is a good heuristic

but js reason about how many objects you're keeping around at any given instant

[cinder zephyr]

it literally is depends

the general strat is optimize for time complexity

but do be aware of the space complexity you have

for interviews

for the real world, please refer to your specific situation, hardware, constraints, and use case

also be aware of how data structures are implemented in your language of choice

That's a map? Ok is it a tree map or hash map?

That list supports appending elements to the end? Ok so then you should know that doesn't run in O(1) time, it runs in O(1) amortizedtime. Can you explain that?

etc etc

[glass peak]

I do wish I had taken a DSA course in my UG but I should also really just learn this stuff a bit more carefully on my own time it shouldn’t be so bad

The amortised thing is just like “it’s usually not worst case” though right? Like on average it’s O(1)

[neat lintel]

Thx

[true zinc]

Yes

[late compass]

Hi

[warm umbra]

Welcome to the server @late compass

[late compass]

Ty

[twin flicker]

u dont always analyze big O

technically

[twin flicker]

expected

[lavish kayak]

amortized is a bit conceptually different than average, it means the average cost of batch jobs.

it's not average in the meaning of probability

[ocean harbor]

@worn walrus did u manage solve the problem at the end?

[worn walrus]

yeah !

[ocean harbor]

happy to hear 🙂

[spring raptor]

[sage canyon]

is anyone here going to Thailand WMTC 25

[ocean harbor]

[barren anchor]

the formula for average depends on probability. And I think amortized does mean this in the CS sense of it.

I have never heard it as something which only applies to batch jobs, either. It's without respect to whether the runs are ran as a batch or in sequence.

[barren anchor]

it's just the average of all cases, yeah. Usually approximated.

[icy heron]

You need to be mindful of what you're actually averaging over though. If you have a hashtable that is less than half full, then insertion is gonna be O(1) no matter what you're inserting. And if the hash table is close to capacity and needs to be reallocated, then insertion is gonna be O(n). But if you're inserting n elements in a row, then this is gonna take O(n) on average, so I guess it's a different average than averaging across the values of a single input. So saying hashtable insertion is amortized O(1) is slightly different than saying that for example quicksort is O(n log(n)) on average

[twin flicker]

what if you have a bad hash function and the keys are clustered

[barren anchor]

I don't think this is true. If you have a hash table that is less than half full - let's say 49% - and you're hashing the exact same value repeatedly, and let's say it hashes to the first position in the hash table, and all the current entries are in the first half of the table, you're gonna be running on a time complexity of O(n) where n is the number of entries in the table on every insert.

it do matter what you're inserting. And what the current table looks like.

[icy heron]

Hmm okay, bad example, but take appending to a list for example. If the length is less than the capacity, then appending is guaranteed O(1), otherwise it's O(n). So the point is that it doesn't depend on the input, it depends on the state of the data structure, i.e. how many appends you have done

[barren anchor]

p.s. I should be clear in my counterexample I am also taking collision resolution algorithm to be linear probing

could be redundant hashing instead, or something crazy complex like rooting trees where keys map to

(crazy complex is an overstatement ik)

[icy heron]

(I mean list as in an autogrowing array, like a vector in Rust or C++)

[barren anchor]

capacity of what?

[icy heron]

The length of the backing array

When the length exceeds the capacity, you need to reallocate

[barren anchor]

you're saying a hash map implemented as an array and you'd expect* append to be a common operation?

[icy heron]

No, forget the hashmap. I'm talking about a list, also called a vector in Rust

[barren anchor]

probably shouldn't use any language-specific terms here, keep it abstract. I got you though. I'm just wondering what exactly capacity means for a linked list.

I guess if it's backing a hash table then it makes sense

but obviously resizing a linked list opens up way more fluid hash table design

[icy heron]

Dynamic array is the term I'm looking for: https://en.m.wikipedia.org/wiki/Dynamic_array

[barren anchor]

I don't usually think of them being backed by a linked list though, because it is the average case constant access time on a balanced table for getting values for a given key that tends to be the entire reason you would use a hash table in the first place

[icy heron]

I'm not talking about linked list, and I'm still not talking about hash maps

[barren anchor]

sure, ok. I got it.

at capacity, an insertion into an array implementation of a hash table would need to resize the array.

you're not wrong there.

I don't think you can just talk about an array in a meaningful way in the context we have here though because we are talking about specific operations

if it's not a hash map, and it's not a linked list, maybe you don't ever even need to handle resizing the subject of your considerations.

who knows? yeah, an array is an array. Dynamic arrays allow cheap insertion / deletion.

(up to their actual maximum ofc)

[icy heron]

No idea what you're talking about. My point is that amortized analysis is not about averaging over the possible values of a single input, it's about averaging over a sequence of operations. And the example I gave was appending to a dynamic array

[barren anchor]

dude

[barren anchor]

firstly, this is just wrong

[barren anchor]

this side point should've been your made point

[barren anchor]

this was not your point

I thought we got past that and were discussing different ways to implement hash tables wrt to specific operations

I guess I'm saying we've got a major assymmetric understanding here

[icy heron]

Okay, sorry, I think we talked past each other 😅

[barren anchor]

this is just not quite right. If you read what I said, you'd see I did understand you.

anyways yeah I think I talked past you

actually I'm being an ass, yeah, we talked past eachother

my bad too

[barren anchor]

I agree with this 100%. I also agree with your earlier point that you need to be aware that average case analysis is not necessarily meaningful without a clear idea of specific cases.

[icy heron]

Yep, for hash maps I guess you need to average in two different ways: an insertion can be O(n) either if the hash function gives a lot of collisions, or if the table is close to capacity and needs to be resized. But for a reasonable hash function across multiple insertions it's gonna O(1) on average

[barren anchor]

yeah definitely

unless your input is 1 identical thing that is always the input!!!!

then you need to discover the god hash

an unreasonable hash function in the sense that it transcends our understanding of numbers and functions

given an unreasonable input like that. But at that point I guess the choice of data structure itself would become the unreasonable thing.

[fresh comet]

[lavish kayak]

I mostly meant that there's a concept of average complexity and amortized complexity and they're a bit different

it can be a gotcha question

[icy heron]

Yep, this was what I was trying to highlight too. For example, you wouldn't say quicksort is amortized O(n log(n))

[twin flicker]

well

its cheap when you use doubling for resizing

if you dont then its kinda shit

[compact surge]

arent there arguments about like what scale factor is best for this

2 is easy and simple to do but not everything use a factor of 2

iirc python resizes using n => n + (n >> 3) which is about a scale factor of 1.125

[twin flicker]

yeah thats just one implementation

[compact surge]

fibonacci numbers are also an interesting choice

[twin flicker]

you can use other scale factors

same way you can use diff pivot choices for quicksort / quickselect

my favorite is random pivot

[compact surge]

the average time per insertion is a/(a-1) if your scale factor is a but also the amount of wasted memory is n*a-O(1)

lmao

making quicksort non-deterministic

but also yes it is still deterministic

[compact surge]

that makes the average time per insertion 1+phi

[versed token]

<@&286206848099549185>. hello this is a long shot but I am really struggling with APA formatting and citation and I know this is only for math questions but I’ve tried multiple other platforms and nothing has helped are you able to help.

[twin flicker]

well you usually analyze expected w quicksort

because worst case is quadratic

and randomized pivots have good expected case performance

[compact surge]

ye

[twin flicker]

you could also do median of medians

[compact surge]

what do you think of algorithms that basically rely on randomness in order to be fast

like imagine if you were given 2 arbitrary polynomials and you wanted to check if they're equal

[twin flicker]

well i like monte carlo algos a lot

simulated annealing etc

[compact surge]

mm yeah i see

[twin flicker]

its just that theyre really hard to analyze

[compact surge]

you could try to expand them both with distributive property (taking a long time), or evaluate them at randomly chosen inputs in modular arithmetic (posisbly a lot faster)

[loud tinsel]

do u know about Schwarz-Zippel Lemma , it states that if the polynomial P−Q is truly non-zero (meaning P and Q are not equal) the probability that this single random evaluation happens to land on a "root" and incorrectly yield zero is extremely low, specifically bounded by d/|S|
(where d is the degree and ∣S∣ is the size of the set). by choosing a "large enough" set S this probability of error is pushed down to a negligible level
https://en.wikipedia.org/wiki/Schwartz–Zippel_lemma

[compact surge]

ah interesting

S is just the number of points you wanna test ig?

or the set of the points whatever

[loud tinsel]

formally S is finite subset of the field over which the polynomial is defined when testing a multivariate polynomial P(x1,x2....xn) test involves selecting a random point r = (r1,r2...rn)
from the n dimensional space defined by the Cartesian product S..S×⋯×S (often denoted S^n)

[compact surge]

oh

i kinda understand ig

just multidimensional polynomials are a bit strange to me

[slow remnant]

[atomic tapir]

No, I am in high school

[slow remnant]

Oh wow...

Do they teach you the biggest number there

Because my teacher says infinity isnt a number

and im like "I dont belive you" but she dont care

[atomic tapir]

A number that is larger than any given number, approaches infinity.

A number that is smaller than any given number, approaches minus infinity.

This is the limited knowledge that I have of infinity.

[whole horizon]

it’s not part of the real or complex numbers

but there are number systems where it actually does exist

there’s usually more than one though

[agile fiber]

infinity is a concept that can refer to several different mathematical things, some of which are numbers and some aren't

[winter swan]

hello

[woven relic]

what if we had a diffrent algebra where positive*positive = negative ?

[agile fiber]

what would negative * negative be

[woven relic]

positive

My idea is basically:

(+)(+)=(-)
(-)(-)=(+)
(+)(-)=(+)
(-)(+)=(-)

[agile fiber]

so multiplication is not commutative

[atomic crypt]

That would just be -1 * the sign of the second number.

[woven relic]

Yeah, and imaginary numbers no longer exist, also exponents now feature a (-1)^n

2^3=-8 under this new Algebra

e^x -> e^x*(-1)^x

however ln(-1) wouldn't be defined

[fresh comet]

[alpine kindle]

let's do a simple calculation
0
= 0*1
= (1-1)*1
= 1*1 + -1*1
= -1 + -1
= -2

this only uses very basic rules of arithmetic

so basically, any system in which this idea for a multiplication operation works must either

1. be really awful and break some fundamental assumptions about algebra
2. satisfy the equation 2 = 0

the second option is not so bad - a lot of "number systems" in more advanced mathematics actually satisfy 0=2 (look up the "integers mod 2" for a common example)

but if you slightly rearrange the equation you see that what you've done is show 1 = -1, so your system of multiplying signs is trivial because negatives and positives are the same

did they change up the months or just rename them?

[old oak]

They had to change them up, since it was 12 months of 30 days each

With 5 "supernumerary days"

[unborn meteor]

demon days

[old oak]

Sort of, they were basically an extended feast in honour of the revolution

[vivid quest]

i know they replaced [st something] days with seasonal veggies

which tbh

would be a good thing today

bc idk seasonal veggies

[old oak]

Yeah, every day was dedicated to something, the way in the Catholic church every day is dedicated to a patron saint.

But instead of saints they went with vegetables

[vivid quest]

ye

[old oak]

Well, "they", it was mostly one guy's pet project

[vivid quest]

unsure about that

bc yk

no anyway

the cult of the supreme being was funny

[old oak]

I mean, the revolution as such certainly wasn't one guy's pet project

But I believe the thing with the patron veggies and the weird names of the months was almost entirely this guy: https://en.wikipedia.org/wiki/Fabre_d'Églantine

[unborn meteor]

(this is what they're called in ancient egypt iirc)

[vivid quest]

oh okay

i mean

just renaming stuff isn't huge

[unborn meteor]

i mean it is now bc computer programs

[vivid quest]

but instoring a made up cult is lmao

[unborn meteor]

January 1 is such an arbitrary date, the only thing it has going for it is that it's close to periapsis

[old oak]

The calendar wasn't really to do with the cult, it was a separate thing

[vivid quest]

yes

i was just listing stuff

[old oak]

The French revolution also instituted the metric system, which was a huge and lasting accomplishment

The calendar was also part of this rationalization drive, to have the months be of equal length and more easily divisible

[vivid quest]

hence what you said about it not having time to implement decimal time

[old oak]

Yep, eventually they had to dedicate all their focus on staying in power and alive, mostly with limited effect.

[unborn meteor]

they also tried having decimal time

[old oak]

And once the radical phase ended, the Directory also focused mostly on keeping things going and themselves in power, reforms were mostly on hold until the Consulate/Empire

[vivid quest]

yes that's what outsider has been saying lmao

😭

[unborn meteor]

yeah

[old oak]

I'm a teacher, I'm used to people not paying attention to what I say

[unborn meteor]

i mean specifically decimal hours, minutes, and seconds

[old oak]

Yep, I have been saying that as well: #serious-discussion message

[vivid quest]

wasn't the directory like a mercantile dicatorship

so they didn't care much about progress did they

just money

[unborn meteor]

oh i didn't scroll back up that far 😭

[vivid quest]

you must also be used to people being late to class

[old oak]

Just staying in power and alive, really. Moneywise it's complicated, since for instance they really screwed over their banker friends (which is why it was so easy to get them deposed and replaced with Bonaparte)

You can keep an unpopular and useless government going quite long if you have the army and the money, but those both went to Bonaparte

[vivid quest]

my teeachers always barely covered that part because it's probably not as "interesting" as the other parts before and after that

bythat i mean

less epic

[vivid quest]

oh ye we know that

[old oak]

Well yeah, it's fair to say that the exciting phase mostly ends with Thermidor, until of course Napoleon's own coup and subsequent wars

[vivid quest]

the wars started with the revolution

not with napoleon

right?

[old oak]

Oh yes, but I mean the Napoleonic wars are their own thing

But yeah, it got started in 1792 and basically kept going until 1815

[vivid quest]

there's so much to learn about that part of history

[old oak]

Interesting times, to be sure

[vivid quest]

also

why do you know so much about that

interested in history?

study it?

[old oak]

Not as such, although my BF is a historian, and as for the French revolution I mostly got interested because of Mike Duncan's podcast: https://open.spotify.com/show/05lvdf9T77KE6y4gyMGEsD

His series on the French Revolution is a great listen

I mean, so are his series on the other revolutions

[vivid quest]
