Fomenko also merges the cities and histories of Jerusalem, Rome and Troy into "New Rome" = Gospel Jerusalem (in the 12th and 13th centuries) = Troy = Yoros Castle.[20] To the south of Yoros Castle is Joshua's Hill which Fomenko alleges is the hill Calvary depicted in the Bible.
this one is my favorite part
wait does he think jerusalem being in palestine is just fake news
if so, are we sure he's not just campaigning for a bold solution to the israel-palestine conflicts
wtf are you talking about
this is in tom dieck its literally how he does classification of coverings over a space B
dont ask for more details im still reading that chapter

Is tom dieck related to grothendieck?
link for precalculus book
ty very much
"one handed reads"
Exactly
After that book
You can fuck 20 women a day
If you are into women everything else is okay too
Ok,This is definitely nsfw
Was ist nsfw?
Not Safe For Work. Content rated 18+.
This wasnt the type of book I was expecting here.
None of us were expecting that
There was also once a guy who told is we all had to read crime and punishment and then proceeded to describe the plot of pride and prejudice
At my school someone in a cs class lecture asked for a link to the textbook in a class of 1000+
And someone shared a porn link
I must ask
How do you have 1000+ students in a class??
CS classes are very in demand
No, I get that but how does 1 class has 1000+ students
Shouldn't the students be divided
Ofcourse for research purpose
Zoom
You let the GSIs and UGSIs manage those sections
Iirc the limit is 500
Recorded lectures, not everyone shows up
Even the paid?
It's definitely doable, my uni does it every semester lol
CS has one more paper compared to others.
Wtf, seems like you’d lose a lot of the benefit of paying for a class with 1k students. More a mooc at that point
Do any of you know what that purple logic book that uses 1 0 and # as truth values is called?
the real limit is whatever the size of the lecture hall can support but online it doesnt matter
i dont really get it, the entry level market is a bloodbath if you dont have coops and work experience though
having a degree helps but its not going to be the important thing
and plenty graduate unable to code
everyone wants to make the big silicon valley bucks
CS goes through booms and busts
Also plenty able to code exceptionally well compared to high graders list.
Everyone can code but not everyone knows complex analysis
Everybody codes* there, fixd
My point was , just attending class doesn't make you understand 'complex analysis'.
just coding doesn't make you able to code
you gotta get beyond the cargo cult thinking that a lot of people start with for programming
cargo cult thinking?
I agree, it is beyond me why anybody would pay to listen to recorded powerpoint presentations. The only times I found lectures useful are when the lectures are interactive as in the lecturer not being stressed out due to fucked up schedules. I guess what they are really paying for is for somebody to look at their code and tell them it is ok.
Cargo cult programming is a style of computer programming characterized by the ritual inclusion of code or program structures that serve no real purpose. Cargo cult programming is symptomatic of a programmer not understanding either a bug they were attempting to solve or the apparent solution (compare shotgun debugging, deep magic). The term car...
Do this maths server have lectures? It would be cool.
I would be willing to pay as well.
it does not
Any ToS preventing this?
no
not that i'm aware of
that said
some degree of mathematics goes on in vc
occasionally
All cs majors are eventually going to become reduntant

if you're talking about AI I have some magic beans Id like to sell you
I think this is a correct statement, but probably not for a while
Not just AI, I think most cs majors cannot really do anything outside of software dev
As the field progresses it will increasingly require more domain specific knowledge
Damn I didn’t realize how big Riley et al math methods is
Nice you have a soft cover of it
Good find
I don't think they make hard cover this thick book 😄. It's already heavy
Do you have more of your collection to show? It’s very nice so far
@hearty steppe I have other subjects. Physics, economics, politics. Maths this much only.
It's good. I just got it 3 days back.
Concepts of Modern Mathematics is a book by mathematician and science popularizer Ian Stewart about recent developments in mathematics. It was originally published by Penguin Books in 1975, updated in 1981, and reprinted by Dover publications in 1995 and 2015.
Are you a student?
How is software engineering?
Good. Interesting.
why do you have these books then
i mean have you read all of em ?
oh it was you who said they have lots of books, like collecting books

heavy collection ngl
do you rent these
No, Once I read completely I give away.
"design patterns" 
yeah their background is often quite pathetic
meh domain experience comes with years on the job but you have to be willing to learn as you go
some people have 10 years of experience
others have the same year 10 times
2009, almost 11 years at the current company
for me
Why would you have software engineers learn the domain when there already are trained professionals with years of experience in the field?
lol
the amount of "trained professionals" with "years of experience" who can't even write fizz buzz is ridiculously high
Learning programming/algorithms is the easy part
you'd think so....
but you'd be wrong
and algorithms don't mean much outside of your cs courses for the most part
might be useful for places that use stupid leetcode interview questions as a gatekeeping method
but the leetcode has nothing to do with day to day
For most interviews what they ask is advanced DS/Algo and rarely we use those in jobs.
What do you actually use?
Stackoverflow
how do you not know how to write fizzbuzz
wtf
like even the inelegant solution
do these programmers not know that divisible by 3 and divisible by 5 implies divisible by 15?
or what
but even then
you can just have 2 checks
yeah
flag = false
if div by 3, print fizz, set flag to true
if div by 5, print buzz, set flag to true
if flag is still false, print the number
print a space
well thats what i mean by the inelegant solution ultra
Do tower of hanoi iteratively. That's the basic one.
is the concept that they're missing just
using a flag to act as an "else" for multiple "if" statements?
Stack Overflow(literal)
Also a lot of algorithm in CS comes with natural recursive solution bcz it's mathematics. Anyone can solve that, iterative is the difficult one.
iterative tower of hanoi doesnt seem that insightful to programming abilities
You mean solve the reccurence?
dont you have to do random adjustments
depending on like
the parity of the total number of discs or whatnot
It's not about programming abilities. It's just for though process.
thats the kind of thing that'd be easy to see in an IDE
but seems tedious without it
¯_(ツ)_/¯
Most of the DS/Algo interview isn't even for solution, how do you approach it is what they check.
No, Use loops rather than recursive calling.
i mean i dont think i'd be able to observe right away that you need 2^n - 1 moves
if i didnt know it already
Hints will be given.
¯_(ツ)_/¯
It's pretty sure that even the interviewers just get those question from leet code or etc..
I have forgotton most of the process. Need to start working on these again.
T_n is minimum number of moves required to do that,if there were 3 pegs
the concept of if statements and remainder eludes them
like even at a conceptual level
let alone get it into code
How the heck do you not understand if statements?
programming requires a little bit of a conceptual leap from jamming stuff in from stackoverflow to appease the compiler gods to thinking through how you want the program to work and adjusting it when it doesnt
some people never make that leap
some people with "years" of experience have never made that leap
it's weird
but it is what it is
we have problems that people need to solve but like if they get stuck we'll give them hints and guide them to it
how they adjust to feedback and figure out that and work towards a solution is more important than what they come up with
"how would you test your program to ensure it works?"
ok "how does your program handle this case?"
also do they ask for questions/clarifications is one I tend to look for me now
because the people that don't tend to also fixate and never ask for help
real world stuff is about getting stuff done, nobody cares that you figured it out all on your own
@molten wave do you have recommend reading material on types and categorical logic aka abstract nonsense?
for types, the HoTT book gives the best introduction to MLTT
Holy shit!
any suggustions for an intro-level partition theory text book? Something at the undergrad/begining grad school level?
What intro level stuff is there for partition theory?
My school has a partition theory seminar and I was wondering if there's any material I can look into that might help me understand what's going on a little better.
look at the papers they talk about
idk much about partition theory but it seems accessible enough
unlike algebraic geometry which takes literal years to get the basics

@opaque birch I feel like it depends what type of partition theory they do idk
Some people approach partitions from a combinatorial point of view
While others (such as Ono) use things like (mock) modular forms to talk about partitions and this ends up being a pretty different point of view
And these two things need somewhat different prereqs
Elements function analysis by Kolmogrov? Good?
there's actually 2 different translatations of different editions of it
i think I read the introductory real analysis version but I found it interesting
I see two volumes combined and total 281 pages. Isnt it too small?
i believe thats fine
Also self study is ok with it?
I read it but I didnt go too in depth
maybe someone else will know
are there any books that look at analysis from a categorical viewpoint?
condensed mathematics
so Scholze is the main person to look at for stuff in this area?
there are a bunch of lectures on youtube by Scholze and Clausen
there is condensed.pdf and analytic.pdf
look up condensed mathematics masterclass
depending if you are an infinity memer or not
are you an infinity memer
gabe
i dont even know what that is
do you read stuff on the nlab 
only briefly if i come across it looking for other stuff

do you like it when you do not have well defined compositions

do you like to mumble about "higher data"

i come from physics/engineering originally and work as a programmer so.... https://twitter.com/davidduchovny/status/913401280160202754
no
Math Bookworm doesn't seem cringe so they're safe
As an actual answer, infinity memer means infinity categories
so categories all the way down?
Thanks! I'm interested in the combinatorial side
Categories all the way up
Okay yeah, I really only know about the latter side of things so don't know what to recommend
Are you interested in algebraic combinatorics?
Yes, very much
Ok let me see if there were some book recommendations from the polymath REU
i think this sort of thing is probably more what i was looking for with the category theory +analysis https://www.maths.ed.ac.uk/~tl/cambridge_ct14/
Anyone have any good recommendations to learn about differential forms ?
Mfw i went to check my email for the book and then see a grad school offer 😂
Congrats!
A lot of these recommendations are particular to symmetric functions
But if you're interested in algebraic combo, that's something you should look into
Partitions come in when you try to index bases of symmetric polynomials, for example schur functions
Is there any analysis website for Tao's Analysis? More eg., explanation etc.
Math Stackexchange
Nowadays they downvote everything. Can't ask such simple question.
i mean they assume you spent like 40 hours thinking of the qn lol
which i would usually like to assume as well ngl
woa
Try to add more context to your problems, format it in good MathJax, show your efforts. You could be forgiven for formatting(not if you do that consistently either), but the other two are important.
Just ask here
Is there a solution manual as well. I am trying to do the exercises.
Git gud
Lol, I’ve asked questions to stackexchange and bountied them and usually it’s no response until eventually I answer my own question, then someone says my first question was wrong without seeing my own answer and I get salty because of course my question had problems, that’s why I needed help from stackexchange and I figured it out 
@gray gazelle your axiomatic set theory questions fit in the #foundations category
The maths stackexchange now is not the way it used to be 5 years back 😦
Your problems might be in the borderline category-too advanced for MSE, too baby for MO. 
Most questions which go unanswered usually fall in this category.
Why don't we have two sites for physics like MO and MSE, why only for maths
I'm a rather recent user, but I agree the overall quality is declining.
Too many homework problems have been repelling the advanced users.
I read somewhere(probably on an MSE meta thread) that there used to be a Theoretical Physics Stackexchange, analogous to MO. Even though it looked good in the beta trial, it couldn't attract a lot of users.
Yep, either this or too broad. I ask pretty open ended questions sometimes which I shouldn’t
I see.
too many people asking HW questions on what used to be MO; not sure if that's a thing in the physics one
PSE cracks down on homework problems even harder.
Like
I still don't know what kind of question you can really ask on PSE
I've had two-three closures there, but at the very least the core philosophy of MSE and PSE differs.
MSE is more humble and the community would receive problems positively in general, provided you show your share of effort.
i can't speak to the quality but https://taoanalysis.wordpress.com/
may help with self study
if you are stuck on particular problems
there's also this which seems mostly dead https://old.reddit.com/r/TaoOfAnalysis/
The first link is helpful. Before I was wondering whether the solution has a easier approach. Seems that it doesn't.
meh if you want to feel the sense of accomplishment of struggling through a hard problem yeah spend hours and hours on it
tbh not hours and hours on it
for me if theres a rather challenging problem
the most effective way is jus think about it in the background
oh I totally agree with background thinking
This is my experience with stack exchange
im totally in favour of them
but if you don't want to use them you dont have to
it's not like their existence harms your ability to do your workflow
and ultimately if you achieve understanding through struggle or seeing how someone else did it you end up in the same place
re posting solutions online my sentiment is the same as well
there's no reason to post your solutions online
again not everyone learns the same way as you
if you don't want them, don't look at them
Best thing is to have a tight feedback loop, get to a point where you think you've solved it and then see if it's the same as the solution given, if it's close but not quite try and figure out what's wrong. If you had nothing, look at the beginning of the proof and stop there and keep trying.
exactly
Did that not too long ago when I was trying to remember the proof of monotone convergence, helped me realize that I was implicitly assuming uniform convergence instead of pointwise and that I do that somewhat regularly. (research supports this method too, not just this anecdote)
That's my usual way of learning things on my own, although exercise solutions are not always accessible(more like, I choose not to refer to solution manuals for some reason).
sometimes though you are just straight up lost and even seeing the solution is enough to get you going on the rest of them
I rather let someone else critique my work, or give me a hint.
With Stackexchange and this Discord, it usually works.
imo having the widest variety of resources is best so people can learn however they find works for them
I still have lots of bad habits like this, biggest one is changing up orders of \forall and \exists (ie. uniform continuity, and other fixing a point and varying epsilon as though there's some specific point in every epsilon ball rather than some arbitrary point in each epsilon ball type arguments) and assuming observations instead of random variables when doing statistics/data science stuff
There are some problems that one may simply lack the requisite knowledge or familiarity with a particular domain specific strategy to make it tractable
I think you gain more by familiarizing yourself with how such a problem is solved than trying to reinvent the wheel
sometimes you're also mostly there but you are missing some nonobvious leap
Yeah, I do think making those sorts of leaps probably becomes easier the more you do it yourself, but I just don't think under time constraints is it very practical for every problem to be a research project
or you see the leap once and realize you're going to need to do similar leaps in other problems which is enough to get you more in the ballpark
Yea. On the other hand, I think the accessibility of solutions can lend itself to people not really thinking for themselves, or maybe just thinking for a little bit for themselves and then just trying to internalize the "right" solution, whereas more could be gained from a wrong attempt carried through to the end
from what I've tended to notice during my degree, the better arranged textbooks were where say the odd ones had solutions but the evens didn't, the odds and the evens would have pretty close steps to go through, essentially forcing people to try to go through https://en.wikipedia.org/wiki/Transfer_of_learning but providing a guide
Transfer of learning occurs when people apply information, strategies, and skills they have learned to a new situation or context. Transfer is not a discrete activity, but is rather an integral part of the learning process. Researchers attempt to identify when and how transfer occurs and to offer strategies to improve transfer.
the shittier ones were just a random hodgepodge of problems that learning one didn't feed into any of the others
Trying to keep you on your toes
Reading Tao - Analysis I for the first time and seeing him demolish all the less than rigorous stuff you get away with in most courses in Engineering and Physics in 12 pages....

hehe
I was actually Eng Phys until I decided I just wanted to get out of school and not go to grad school
electronics was the closest non honours so I didn't need to do the thesis rigamarole
@gray gazelle What made you start analysis? 
it's interesting
Ohh good 
damn 11 years
Time flies huh
but lets make it go faster
cause 2020 and 2020.1 (2021, but it's still 2020 except the latest version) has been pretty shit
I mean duh
any refs or advices pls about good book for trigonometry (circles and triangles) ?
SL Loney's books
Which standard are you?
What book is recommended for a rigorous intro to predicate calculus. I have tried to read a set theory book and realize I am on over my head.
What's a predicate calculus--> Applied calc?
I think Type Theory for Functional Programming does a good job w the theory with an eye toward type stuff
(i am not a programmer by any description)
Oh, is this the same dieck as the algebraic topology dieck?
Yes
where are its eyes
Oops wrong channel
Yea sorry about that
i havent seen chill in so long
COMPACT LIE GROUPS
have you been exposed to the averaging trick?
what is the averaging trick
what is the averaging trick
lmao
since a lie group is compact, you can integrate over it with no issues, yeah?
indeed
yeah mmm hmm
you can often construct things on compact lie groups or manifolds acted upon by compact lie groups by integrating over the group
one example is a bi-invariant riemannian metric on the lie group (or possibly a group-action-invariant metric on the manifold being acted upon)
interesting
(all lie groups are orientable too so you don't have to worry about that)
I can't say I'm particularly surprised that a structure with two of the nicest mathematical attributes has useful properties in smooth manifold stuff
rank the adjectives
- compact
easily
all good things are compact
on a compact lie group you do this
so you're basically averaging over G the things you get by "right-translating" the original metric
and if you do the computation you get a right invariant metric!
Is that a spivak question
it's from do carmo's RG
Ah
spivak doesn't really touch on riemannian metrics
everything's a submanifold of R^n so he just uses the induced metric
COMPACT LIE GROUPS
COMPCAT LIE GROUPS
DID SOMEONE SAY COMPACT LIE GROUPS
YES
any compact abelian lie group is a torus
Yeah that's true
Apparently the key to this is that the exp(X+Y) = exp(X)exp(Y) when [X,Y] = 0

so it cannot be affected by bi people
what conservation law does this represent according to Noether's Theorem?
the law of joe @gray gazelle
If I'm self-studying a book, what's a good rule of thumb for how many questions to go through? I'm working my way through Rational Points on Elliptic Curves by Silverman and Tate, chapter 1 has 22 exercises (almost all of which are proofs) and I've so far done the first 10 over the course of about a week. I'm more than willing to go through every single question if it's necessary, but I also would rather not waste my time if it would be better spent doing other learning (like the next chapter, or the homework for the actual classes that I'm in).
That depends on person to person. Usually if you feel comfortable to move on
I don't really think there's a great answer. Silverman Tate you definitely don't need to do every single exercise to understand the material, but it's hard to say how many you really should do. I think it's mostly up to how well you feel like you understand the topics. Another option is to look up a course that used the book and do the exercises that they recommend but
I prefer skipping the exercises I know I can answer with barely any effort
I’m also a masochist.
Like honestly I’m usually a semi-completionist when it comes to psets these days
Honestly going for the hard questions sounds like the right thing to do; it'll certainly help more than just going over the easy ones.
Some problems can be trivial enough while the ones that really test your understanding and are demanding your attention are the ones you should work thru
But you also should check to make sure if those harder problems matter at the end of the day
I skipped a whole section of linear algebra application problems one time as an example because quite frankly, they were overly trivial and quite random
As an aside, does an average of an hour or two per problem sound reasonable for an advanced undergrad book, or am I working absurdly slowly?
Some questions only take me like 30 minutes, one took me two days and I wound up asking for help here, but so far if I have a reasonable grasp of how to go about tackling a relatively tough problem I tend to take an hour or two on it.
So here’s the thing. Don’t worry too much about how long it takes to solve a problem. It seems many people mention that certain problems require certain levels of knowledge and might require a certain amount of work to be done to appropriate a solution.
You can always look up on average, how long it takes a seasoned math major to solve certain kinds of problems maybe?
Like get an idea for an exam how long it should take you to solve certain problems by simply looking that up in a search engine I suppose. Usually that strategy works for me.
Thanks
Math Exchange website should have an answer for this already I’m imagining
No that is very reasonable
I don't think this is really something you should think much about though
Depends on your goals, but if it's just understanding, take your time.
Yeah, I'm not super concerned about speedrunning the book or anything like that, but I'm reading it as an introductory book on elliptic curves because I want to get a solid foundation in some of the more advanced areas of number theory before I apply to PhDs in a couple years. I have a reading list with a couple books on it already that I also want to eventually get to.
you can always do a pass through of a book or books to get the lay of the land
without necessarily doing all the problems upfront
or focusing on grokking everything
in fact in a new area that may be helpful and get you exposed to some of the terminology and allow you to see what is highlighted for when you deep dive
ie pay attention to what terms are being thrown around all over, what theorems are being used regularly
Yeah, I did a skim of the entire book in a few hours before I started working on the problem sets.
wait
@gray gazelle
I was just scrolling through history on a totally unrelated server


What I say is attempt 2/3rds of exercise, solve anywhere between 1/3rd and 2/3rds, ideally closer to 1/2
That way you aren't doing so many you feel bad, but you're doing enough to learn
What are some good books on quantum physics for those with a strong linear algebra + complex background and not so much physics.
I enjoyed reading townsend as someone with that exact same background
I think a standard book is Griffiths but I don't know if that's good for 'not so much physics'
Either way 'physics' manifests itself as some conservation laws usually, which are just constraint equations more than anything
Should I give a motivation?
I did some quantum machine learning and just learning about quantum circuits and the like inspired me to want to learn more.
Well you probably should be more specific than 'quantum physics'
I assume less dynamics and more statics essentially
Well I'm woefully inept to comment on quantum circuits/quantum computing so I can't say
Qubits, unitary matrices, quantum circuits, hilbert spaces, different gates.
stuff I learned about for the competition i did
but I figured maybe studying some physics would give me a better foundation.
I don't understand what entanglement even is.
The field is interesting.
Maybe I should look more specifically to QML topics/courses.
Hmm I feel like Griffiths would be a good foundation, but you probably won't get entanglement from it - a higher level book would probably be better
If there are no books perhaps surveys from Reviews of Modern Physics would be good as well, they are rather comprehensive on the topics
Nice
there's a version on the library that shall not be named that has those supplements spliced in
there's also a solution manual floating around if you are doing self study
mainly I liked how it tries to cover as many topic areas as can be reasonably gone through
griffiths might go more in depth into the nuts and bolts
but this will expose you to the field
and you can branch out from there
I’ve never heard of Jay Cummings
"In some ways, 2 is the oddest prime."
This video shows how anyone can start learning mathematics , and progress through the subject in a logical order. There really is no finishing point but this will get you through all of the basic undergraduate mathematics from start to "finish". I also included some graduate topics.
Here are the books that showed up in this video(in order) on ...

Oh I love Bri he’s dope
in this pandemic, it's kinda hard to got to library to borrow or buy book :/
I've frequented a certain library to borrow books a lot in pandemic. 
Currently working through it; it's a good book!
I have started the Set theory of Tao-1
Advice: skip it.
Learn set theory from Velleman or any introductory set theory/proof book
Tao's introduction of axiomatic set theory is too intimidating and unnecessary for learning analysis, at least. Probably revisit chapter 3 before starting chapter 8.
What's actually good in Tao? Ppl say second chapter is long and over explained. 3rd chapter can be skipped. Are rest of the chapters like that? 😄
No
Long and overexplained might look bad to those who already know some stuff
But being walked through wordy proofs is a boon as a self-learner imo
Plus, his explanations and presentation are extremely neat.
No, may be 8 of them fully and 5 of them partially.
ah nice
Have you also read TAOCP
What's CP? I don't know. I am reading TAO-1.
And I have ordered
Don't know how good is it.
lol
taocp is knuth's magnum opus
the art of computer programming
That I have PDF (and I haven't read it yet) so can't count in books. The Book set is very expensive by Indian standards. It's 200 dollar. for eg the above book is just 10 dollar.
You randomly buy any book ?
@gray gazelle No, I buy computer related as I am a software engineer. I buy phy+maths+fictional+economics+politics+gk books bcz I like reading them.
Nice.
I liked that there was clearly a lot of care to the examples and proofs being a nice progression
and gotchas with stuff
Yes!
Without some mentor help I am not able to verify whether my answers to exercise are correct or not.
Especially it is asking to use particular axioms.
You can ask in the help channels here.
imo you probably wont develop a feel for what makes a good proof without feedback from others
it's just like going through the code review process at work
"Programs are meant to be read by humans and only incidentally for computers to execute."
at least thats the impression I get (still early with actual proofs)
reading mathematics made difficult, is it weird that I'm not really seeing anything new?
I wonder what that says about me
it says you have achieved oneness with the abstract nonsense
smh my head, Z is a coequalizer not an equializer
but also like, coequalizers is just one of the ways how you make higher inductive types
I guess that means I am the guy who breaks people's legs
Can I use latex in MS Word to write my proof to show it here?
Or any alternate?
I don't think MS Word can be configured to use LaTeX
I just suggest you start with LaTeX on Overleaf.com
If you're going to be self-learning maths in the time to come, it would be an indispensable skill anyway
if you saw the amount of cringing people were doing looking at Kripke's paper earlier
you probably don't want that
Yes, But the issue is that I won't be able to give time consistently.
So paying 120$ would be waste for me I htink.
Huh
oh
Overleaf is free to use
what editor do you use for work
What are you looking at?
It's asking me to register and use free trial for 1 month.
Let me get the link
overleaf isnt free anymore?
Yeah, go with the student one
I didn't click Student earlier, thinking will ask for college name , ID etc..
Nah
Registered, and any example link where some mathematical notations are used?
Use one of their maths notes templates

For some reason I could not make VSCode compile my TeX 
i concur with this statement
getting the stuff set up at the start is a bit annoying
but then it pretty much just works
Overleaf was just get-set-go for me haha. ¯\_(ツ)_/¯
yeah I hate setting stuff up
always a pain
it's why I no longer use linux for stuff
all setup all the time
I use linux for nearly everything
Guys I actually got some additional unexpected benefit using overleaf. Thanks 😄
it's like solar panels, one time cost at the start, but it pays off as you use it more
to mean it's more like you have to keep cleaning dust off the solar panels to keep it working
yup
everyone factors in the upfront cost
nobody tends to factor in maintenance
Any book recommendations for combinatorics and graph theory? (Not a discrete math text but a separate treatise).
Preferably peppered with rigour
with rigor 

@cobalt arch you should literally go learn Lean and then start contributing to MathLib and formalize an entire undergraduate curriculum
then you will finally achieve peak rigour
actually don't contribute to mathlib make your own mathlib
the most profitable area of mathematics


Maths and Profit are extreme ends.
At this point in time recommending me books is a tongue in cheek 
For some reason
appears like that to me:
Thank you Jesse for the recommendation!1

I haven't read it but Bona - A Walk Through Combinatorics gets recommended a bit
Yes!
Strongly recommend.
it's a maze that's constantly permutating out from underneath you
Combinatorics is truly giga-brain.
Like, I'm generally clueless while writing proofs in analysis and elsewhere, but the cluelessness intensifies with combinatorics because there are literally so few tools at your disposal
Is graph theory a branch of combinatorics?
You have to resort to great ingenuity to set up an argument which can make use of those tools
What about a drive thru combinatorics
Only Gowers has a license 
I think so?
i love how every combinatorics book has the subtitle "NOW WITH EVEN MORE GRAPH THEORY"
i should take combo at some point
This book's cover page looks like those useless math books I studies during my HS.
What makes Calculus by Spivak an Intro Analysis book?
it introduces basic topics from analysis with the assumption that you're somewhat familiar with calculus but not with abstract mathematics
What is analysis 😳
this cover is so ugly
topology but you only care about metrics
and topology is algebra but you only care about the algebra of the union operator
everything is algebra?
everything we can actually do is linear algebra
everything is algebra.
well this is oversimplifying it
actual engineering moment
algebra is the category theory of concrete categories
and category theory is just physics
like theres no "but"
its just physics
catego-

so in reality you should just go straight to math phys
GO STRAIGHT TO MATH, DO NOT PASS GO, DO NOT COLLECT $200

intro diff geo books?
introduction to smooth manifolds by tu, differential geometry of curves and surfaces by do carmo
This is similar to looking at math definitions, coming across and unfamiliar term, and entering a loophole figuring out definitions
well i was shitposting
I understand 😆
if you want like
a more serious answer

the motivations for introductory analysis are "let's actually understand what's going on when we do calculus"
since calculus as usually presented is a bit imprecise
arguing with vague notions about infinitesimals and whatnot
it works but analysis:
(a) lets us understand why it works
(b) lets us create a framework for what properties calculus formally "requires" so we can build off of it into exotic settings
the real motivation for introductory analysis is (b)
to be a bit more mathematically savvy about what analysis studies
it studies limits, convergence, smoothness, continuity
this is a bit vague since one can say e.g. topology also studies continuity
the way to clarify this is to say "well analysis studies analytic continuity" which is about as useless as it is tautological
yeah apparently i got emoji perms when mniip restructured the roles
so
corruption
I see
is unironically a great emoji
for like
"I want a thinking emoji but dont want the sarcasm of a usual thinking emoji"
i might remove
but i think
is here to stay

We are definitely missing some emojis
For example, this one should be an emoji
There could be a better emoji for a smug fuck you, I've been using
for this, it's okay/it works, but I've wondered about better one
theres 
But I want a smiling one
I guess smug is not exactly what I'm looking for, but something like that
there are 3 types of emotes
i think i am a better person than you: 
i think i am a smarter person than you: 
i am making a joke and am too cowardly to make it without making my sarcasm obvious: 🧠
every other emote fits in one of those 3 genres
I guess the yellow face is sort of what I'm looking for, but it should be a anime girl and not be doing a weird eyebrow raise

Ah yeah sort of like
but it's not quite what I'm looking for
It's not "fuck you" enough
Or maybe "get fucked" is more what I want
youre welcome
Woog emotes:

Mniip emotes:

hmm the rest of the body was optional namington
are you a fan of the boob sword girl 😌

i like the reading frog
it feels like
idk
the words aren't there
but
yes
it gives off Hmm vibes but better
Now I read 
lmao yeah, for me it's the nearly closed eyes, like the frog is thinking "wtf am i reading rn?"
yeah lol
Anyone got any good suggestions for complex analysis textbooks?
ahlfors
@reef oar Nice nickname
Thanks
Is that the name of the author?
It's an unfortunate name
Jesus when was the last edition of that book released

yeah he really likes to get down on ahlfors with complex analysis
Schlag is good
Kind of assumes a little geometry before you start though
Anything particularly ugly?
Or just basic angle and trig stuff.
No worries! The goal of the book is to build up to and study Riemann surfaces so maybe not what you’re looking for!
Reimann surfaces are lit
I really wanna learn them
Ye they are cool
Churchill I think is the one my undergrad university uses. I hear people like that one
As Springer texts go it's not bad but some of the conceptual explanations are a little lacking
I'll look into. Do you know what the most recent edition is?
I think it’s actually in its ninth edition now, but you can get the earlier editions for pretty cheap
And if all you want is supplemental instruction, I think that’s fine
The struggle ∈ ℝ
RIEMANN SURFACES
@tribal kernel did someone say Schlag
What is a good group theory book for an under graduate in Engineering? Most basic possible.
What's your experience with proofs and Lin.Alg. before?
Linear Algebra in HS + 1 year under graduate.
Nothing specific in proofs.
So, you haven't done any proofs using induction and similar?
Yes, induction I have done. Don't remember any specific chapter for that.
I get it , contradiction , induction etc. I have done. Not advanced only undergraduate stuff in engineering.
Ah okay -
You can take a look at Artin's Algebra as it's really good Algebra text.
If you can handle Linear Algebra stuff like subspaces and inner products - Then you can take a look at Jacobson's Algebra.
Not advanced only undergraduate stuff in engineering.
Well, you don't see anything group theory specific in Engineering unless you look at extremely specific fields in Engineering.
No knowledge in subspace. So I should go with algebra.
Yup - Artin's Algebra it is
I might go with something a little more gentle like Gillian or Fraleigh
Any books on quantum physics?
Yessir, I think we’ve talked about him before
Hi
Books on differential geometry 😮
for classic, do carmo's curves and surfaces
otherwise, there are many good books. the most common recommendation is lee's introduction to smooth manifolds (for good reason)
there's also the watered down version by tu called "introduction to manifolds," still a good read but far less comprehensive and difficult
Thanks, im doing physics but i'm really into maths
topology is a requeriment?
or just basic knowledge
for at least the latter two books, it is required
for the first one, no
Okay, really thank you ^^
Bumping Lee’s Smooth manifolds. The follow up on Riemannian manifolds is also great and while they do reference topology, it’s never really difficult stuff in my experience.
anything but "Lectures on Differential Geometry" by Chern, Chen, and Lam 
Pls don’t use Schlag as a first book
At the minimum if you do make sure you’ve seen manifolds or sometbinf
It’s not impossible but I think it’s more pain than it’s worth
Anyone have any book recomendations for learning about reductive groups
no scheme theory pls
Oh and Spivak’s series on differential geometry is long and rambles a bit, but it has great exposition
i dont know it yet
Oh yeah I know it's a theme of mine to just walk in and say "Did someone say X?"
Lol no worries my man. Schlag has grown on me
How is Reids undergraduate algebraic geometry
I think it's fine
Hey everyone, is this the right place to ask for where to find some exercises regarding boolean algebra?
If there are any online PDFs I could find perhaps or something like that
can we discuss books here ?
See description
Favorite discrete math book? Any deviations from the two recommended by the Math Sorcerer video?
He recommended starting with that over pre-algebra/etc to nail down proofs early on
For discrete mathematics I recommend this book https://www.springer.com/book/9783540292975
This comprehensive textbook on combinatorial optimization puts special emphasis on theoretical results and algorithms with provably good performance, in contrast to heuristics. It has arisen as the basis of several courses on combinatorial optimization and more special topics at graduate level....
for a beginner?
It was the recommended book for my intro class
So I would think it is accessible to someone having no prior experience in discrete mathematics and having maybe a bit of experience in regards to basics of proving stuff
ok
From the episode "Dammit Janet!".
All copyrights belong to more talented people.
what are some general topology books you have found useful/liked outside of the standard Munkres/Topology Without Tears?
not really topology but i like ziemer’s analysis
it has topology / measure theory / functional analysis
Do you have an issue with munkres? I guess my view of point set topology is that even a basic amount of it can be good/sufficient
Eg, knowing the basic definitions, knowing that "good things happen in compact/hausdorf spaces", etc
mostly looking for other things to read at that level
bourbaki /s
lol
the pinned topology book is pretty gud
lee's introduction to topological manifolds, although it's maybe a lot less "general-topological" than the other books
it does do a fair amount of general topology though
but a fair chunk of it is intro AT
(and intro AT > GT)
on the other hand, if ur goal is AT, you could read "topology: a categorical approach" and probably jump straight to dieck no problem.
no problem
:egg_hank:
that is not how id characterize reading dieck
regardless of categorical familiarity 
trivial stuff 
virgin trivial problem vs chad trivialization
dieck is good but there is definitely some wack errata
like theres this one part where he applies a lemma in a way that totally doesnt work lol
imagine applying results in contexts where they make sense
this post made by choice gang
who the fuck puts their lemmas after their proofs
thats the more egregious thing here
that is not the problem
it's the real problem
bad opinion
read the statement of the lemma and then read the 2nd paragraph
its not just me right
like this doesnt make any sense lmfao
the lemma applies to open coverings of B x [0, 1] except the analogous space B in 3.2.2 is actually E 
Hartshorne has a proof where he goes “by Proposition / Lemma X...”
And not only is Proposition / Lemma X below it
It’s just a reference to Matsumura
Or something like that
based.
eventually textbooks will just be an unreadable list of references of references of references to books that u can access anymore
this is the standard of the field though
no one in AG actually proves anything
they just cite EGA in new and innovative ways
AG is really just the study of the permutations of the theorems of EGA
And FGA and SGA
Is it just me or is Dieck ridiculously terse
he is
in some ways its good
it forces u to fill in a lot of gaps in arguments urself which is good for understanding
but sometimes its cringe because you think you dont understand the argument when its actually just uhhh
wrong
Some people say Munkres is terse
But to me it's more like, to the point
Things are clear, but not pontificated about
Whereas Dieck just jumps a lot of stuff
Sure, yeah
also if dieck was fully detailed in every proof itd be ridiculously long
But its also funny, cause at like the beginning of the gt recap, he's like, "oh yeah, you may not have seen quotient"
lmfao yeah
And then he presents quotient in like one paragraph
dieck as a first intro to AT seems brutal honestly
dieck if uve never seen a quotient space before sounds
death
I'd prefer just not giving proofs then
Instead break things into small problems
eh i think thatd be wayyyy harder though
You'd have to break proofs down quite a bit
I mean it's a pretty standard graduate presentation
Definition theorem proof
With mistakes to challenge the reader
xd
As an undergrad, you learn from exercises, but the grad student needs to transition to learning from realizing the text has a mistake
ah yes
F_b defined using itself
moth cant you see? it has a different pixel, its a different character
the one is F
the other is F
Face_book
also when the book whips out a problem with notation that hasn't been defined
fortunately it's standard enough that you can find what it means with some digging
another fun situation is when the book relies on a slight technical redefinition
or uses an opposite of a convention
"larger" and "smaller" topologies are a fun one
because these are used in opposite ways
to be fair, in my case im literally using like a 2013 beta version of a now finished book i believe
in like 2017
(because im roughly following the schedule of a 2014 course that used that book)
is spivak calculus on manifolds the best textbook to learn multivariable well?
or should i stick with baby rudin
I wouldnt do it with either lol
@clear sail would this be your first endeavor with multivarable? Because choosing a book depends on how much experience you have with a topic and how much depth/breadth you want
all abstract math books are terse because abstract arguments are impossible until they click
but once they click you become incapable of remembering
what was hard about it
in the first place
Does anyone know a good book or script about measure theory for self-study?
Yeah what level of measure theory?
There’s about 4, but I could probably only point you to maybe 2.5
Actually 2 or 1.5ish, measure theory is pretty broad
Introduction to measure theory
People seem to like Royden (I haven’t used it). I used Rudin and thought it was good (makes a good reference text later too). On the probability side there’s the first two chapters of Billingsley which would bring you up to speed at least with Lebesgue measure
Rudin introduces it w a heavy eye toward a specific measure which lets you dip your toes
but yeah you need a real measure theory book to go further
I would just say to make sure to learn at least a little about Radon measures in the context of duality
Treves has a book which covers this very nicely in like 10 pages actually, iirc, so maybe don’t worry about that and just read that section from a pdf somewhere
Schilling duh. #books-old .
Its the best by far.
If you can cope with chapter 3 you'll probs be fine.
At least that was my experience.
Maybe my opinion is biased. 👀
Yw.
Link won’t work for me, but it looks like it links to Princples of Mathematical Analysis, we’re referencing Rudin’s Real and Complex Analysis
oh
Please don't directly link to copyrighted materials.
Is there such a thing as a begginer module theory book? Can one/ should one jump from linear algebra to that or would i be missing a lot of prerequisites regarding groups?
I would appreciate any group/module theory book recommendations
shouldn't you do intro abstract algebra first?
well module theory is part of abstract algebra
but im not sure why youd want to start with it
ostensibly you dont need the theory of groups but you do need the theory of rings
the field theory necessary to understand vector spaces (hence linear algebra) is very minimal because fields are very well-behaved (and you probably covered most of what you need to know in middle/high school)
the same is not true of rings
(though to clarify: you can speedrun most definitions of vector spaces in a module context and you'll be able to parse them; it's just there's a lot more module-specific material covered after that which you need ring theory for)
introduction to tropical geometry books?
this stackexchange answer might be relevant https://math.stackexchange.com/questions/2848922/tropical-geometry
thanks
definitions of vector spaces in a module context
I am not sure what u mean by this
like
taking notions like basis, quotient space, subspaces, direct sums, and those sorts of constructions
and changing them to use modules instead of vspaces
linear maps to module homomorphisms, that kinda thing
Oh sure, but it does depend a lot on what type of ring it is i am guessing? Are the more general constructions made assuming the least structure of a ring?
in some cases the changes you need to make are minimal, in others you want hypotheses like your ring being a PID or the thing you're quotienting by being a prime ideal
but typically those definitions arent radically different
And yeah, i guess i'll just go with an abstract algebra book, any recommendations?
I was thinking of getting either "A book of abstract algebra by Pinter" or "Elements of abstract algebra by Clark" has anyone given a shot at one of these?
check l*bgen and see what book suits you best
I mean, i just wanted some reviews outside of amazon's
Have you done Linear Algebra before?
Yeah sure
Is F.Klein's book on the quintic and icosahedrons good?
By the way.. on linear algebra.. for a first course in it. Which would you pick?
Linear Algebra:
- Introduction to Linear Algebra, Serge Lang
- Basic Linear Algebra | T.S. Blyth
- schaum outline linear algebra
Schaum
Stop
Pinter is a rather baby book, I haven't heard about Clark before. Dummit and Foote, Jacobson, Artin are the standard recommendations.
Dummit and Foote is like a dictionary tbh. I dislike it. Artin is good though.
that is... not how id describe d&f
in fact, if theres a flaw, i'd say it's that it's the other way around
it's really doting
and full of lots of exposition that doesnt really illuminate significantly more than a less wordy text
i still like the text personally but i may be biased
since its what i learned out of
i dont think its a good reference though because of its rambly-ness
Yeah there a tons of examples in D&F
ya, I would never use d&f as a reference text
but it's definitely amazing for self learning
it goes into excruciating detail and has extremely easy to understand proofs
and the exercises are wonderful
Wtf there’s a massive jump 
Yeah I believe you're refering to schaum?
Yeah, the difference between Lang and Schuam is pretty massive
I know people have nasty things to say about it, but Aluffi works for me when it comes to algebra
nope i took a course on it but i feel like i didnt grasp the concepts well enough
I have to admit, all the shit like curl, divergence blah blah blah make no sense almost
In grasping the concept, I used Multivariable Calculus second edition by Briggs, Cochran and Gillet. It’s quite intro-y but really good for teaching it with the aim of understanding
Based response
Rigorous text on topology?




your doing
