i literally copy pasted from your message...

rocky shuttle
#

[waɪ] is just "y"

leaden torrent
#

yes

#

i am referring to the diphthong

#

are you mixing up broad and narrow transcription?

rocky shuttle
flat harbor
#

i distinctly remember there being an animal that honked in a [aɪ]

leaden torrent
#

[ai] is often rendered as /aɪ/ in american english, so [wai] would be /waɪ/

rocky shuttle
#

Wikipedia says [aɪ pʰiː eɪ] for IPA

leaden torrent
#

huh

#

maybe my style guides are outdated then

#

mb then

#

i distinctly remember being taught it as [ai] with canadian raising changing it to [ʌɪ̯]

#

i remember because i always forgot which was which lmfao

#

but maybe that was an old style convention idk

rocky shuttle
#

so, idk anything about phonetic notation, what's the difference between broad and narrow transcription?

leaden torrent
#

roughly speeaking, narrow ("phonetic"/square bracket) transcription seeks to capture ALL of the details of the pronunciation of a character

#

whereas broad ("phonemic"/slashes) transcription captures only the details that are relevant to a native speaker

#

as an example, some people pronounce the "t" sound in "water" as a flap [ɾ] instead of a [t]

#

especially north americans

#

but to an english speaker these are not phonemically distinct --- they do not affect meaning

#

it isnt even a matter of "you can tell that they mean the same thing", its a matter of "you dont even consciously notice the difference except perhaps in accent-placing"

#

so these two realizations of "water" would have the same phonemic representation but a different phonetic representation

#

the broad transcription is /ˈwɑtəɹ/ (or perhaps /ˈwɑtər/)

#

but narrow transcriptions might look like [ˈwɑtɚ], [ˈwʊtɚ], [ˈwɑɾɚ], [ˈwʊɾɚ]

bright hill
#

Sure, reek

leaden torrent
#

i personally say [ˈwɑɾɚ]

rocky shuttle
leaden torrent
#

[ɚ] vs /əɹ/ is another distinguishing factor here

#

an english speaker thinks of the "er" in "water" as a combination of the "e" and "r" sounds

#

(and in nonrhotic dialects like received pronunciation, the r isnt pronounced and instead the vowel "trails off")

#

but it isnt actually realized like this phonetically

#

its realized as a rhoticization, not two separate sounds

#

[ɚ]

#

or in received pronunciation, [ɐ]

#

but the difference between [ɚ] and [əɹ] is not phonemic in english (regardless of dialect)

#

it does not carry information about meaning

#

so the broad transcription represents them both in the same way

#

like how it represents [t] and [ɾ] both as /t/

rocky shuttle
#

I see

#

I kinda understand why you were confused by [ɪ] then

leaden torrent
#

this is common across languages, e.g. the japanese character す is most commonly realized as [sɨᵝ] or sometimes as [sɯ̟ᵝ]

#

but its almost always written phonemically as /su/

#

maybe /sɯ/

rocky shuttle
#

it's funny talking about phonemes when you don't know how they're supposed to be pronounced

leaden torrent
#

[sɨᵝ] is like, imagine saying "suki" but you keep your lips together during the "su" part and dont actually pronounce a vowel

#

so its almost like youre holding the "s" and never saying the "u"

deep mango
#

zan desperate to find a way out of this conversation

leaden torrent
#

this process is known as elision

#

[sɯ̟ᵝ] is the same thing but with an unrounded "u" sound inserted

#

whereas [su] is... exactly what it looks like

#

"sue"

#

i sent an email to the head of teaching in the mathematics to discuss moving from cs to math-cs

#

idk. when i think of moving to math i get all tingly and focused like a fever rush. I'm not sure why i want to do more math and im not sure if it'll be good for me

rocky shuttle
#

#

Doing math is good for the soul

lavish kayak
#

when i do math i feel like someone is pointing a gun to my head and tells me to solve it NOW. the whole world fades away and it's like something else takes over and in the end i either get the result or i get a bunch of stress and meaningless scribbles. I'm still conscious but it's like i'm fearful.
i want to learn how to do it without the tension, but i can also just choose to engage in it less

sharp mulch
#

Ummm

#

That sounds stressful

zealous garden
#

Why does it feel like that

#

Just like, math bro

lavish kayak
#

I know myself well enough to know im not bad at it. im also not a genius. it's fun, interesting, challenging, but it's like theres an unhealthy part insideof me that attaches to it

#

sometimes it's like that sometimes it's not

torn willow
#

So wait, what's cs if math cs is a different thing

lavish kayak
#

cus i feel like if i won't be able to solve what im working at i'll be a failure.
and it's absurd and i intellectually understand that this feeling is bogus but the strength of the almost-fugue state i get in is too much.

lavish kayak
#

so calc 1/2, linear 1/2 but easier, a int. to logic course and a discrete math one, plus you can take more theoretical courses like computability

#

but you won't do any of the usual year 2 math like int. to analysis and the general level of everything is lower and more practical

#

cs-math is like normal math with some of the year2/3 math courses exchanged for CS courses

cinder zephyr
#

Discrete math for CS has a larger focus on induction, graphs, trees

#

Some definitions like complexity classes

#

State machines

#

Stuff that isn't in a normal intro to proofs course

#

Also less focus on stuff like set theory

lavish kayak
#

in the past 2 months i've been practicing vipassana daily and it helped me deal with this issue.
my dilemma is that i can confront it head on and take on more and more intense math, or just do a smoother university ride and if I return to math, return when my skills at understanding myself and fixing issues like that are better

#

so it's like -
have a very intensive univeresity life, but get a full mathematic education
have a smoother university, one where i can learn better how to be happy, and hope that at a later point of my life i return to math and pick up those skills.

torn willow
#

I mean do you want an intense life

lavish kayak
#

theres a part of me that does. some part of me likes the intensity, the scale, the pressure.
the other parts are like "dude wtf"

cinder zephyr
#

I'm a pure math major but have taken many CS courses

#

Gotten internships, TAing CS courses

#

It's worked out

#

So know that you aren't necessarily closing any doors

#

And so if you want to do more math courses and less CS courses then the switching may not be a bad idea

torn willow
#

I don't think it's that kind of a problem. Seems more psychological/personal

cinder zephyr
#

Ah

torn willow
lavish kayak
#

there's an element to both

#

i think i have a misconception in me that if you learn math you have to be a genius if you want to find work

#

i don't really know whether doing math and being average as a undergrad will make it hard to live

#

it might be feeding the problem and causing me to stress

#

can you lead a comfortable professional life if you're average as a math major?

river moon
#

there's tons of people, especially in compsci, who know very little math and live quite nicely

how are you undergraduate but you're in 12th grade

cinder wind
#

I'm doing lots of things on my own

#

Roles are meant to reflect knowledge and interests, not (necessarily) actual placement

#

Is my understanding at least

cinder wind
#

like I'm not even attending school math classes

lavish kayak
cinder wind
#

I spend that time studying university stuff

lyric wing
#

dam

#

so you just dont go to school?

cinder wind
#

the rest of them I attend normally

lyric wing
#

nahhh

cinder wind
#

of course I take exams from the subjects which I don't go to class but I can easily get a 10

lyric wing
#

how can one be good at languages and math at the same time

cinder wind
#

idk life's weird

vivid halo
#

some people are good at spending their time on multiple things

lyric wing
#

stop being good its not fair

#

anyway so you're in high school or univerisity

cinder wind
#

I'm in the last year of highschool

#

here we call it 2nd of Bachillerato

lyric wing
#

i see

#

so you gonna go to university in a few months just like me

cinder wind
#

but however I'm not as good with languages as with maths

#

I mean I can learn laguages pretty quickly (i.e. english) but I wouldn't say I'm gifted

#

rly? cool

lyric wing
#

yeah

#

being smart = correlation with being better at everything lol

cinder wind
#

highschool maths are very easy for me so I easily get a 10 in exams without even attending class

cinder wind

#

you know i always thought it was weird that all the smart mfs are skinny

shouldnt your brain operate better if you're more athletic

but i guess the people who are good at sports and smart at the same time just don't exist because they don't have time to do both

lmaoo

cinder wind
lyric wing
#

all downhill from there

cinder wind
#

well you seem to get along with maths pretty well

lyric wing
#

yeah but not really

#

i should study more if im gonna be good at it

#

but i dont think im gonna be a math major or anything like that

#

im debating the importance of knowing that the derivative of arcsin is 1/sqrt1-x^2

#

i think knowing that you use taylor polynomials to construct buildings is more interesting but the deeper you learn the closer you are to being a scientist or engineer at that point

I'm planning to study a math degree with its PhD

and then the physics degree

how would I make rigorous the idea of taking a discrete relationship and turning it into a continuous one? namely, I want
$$\text{discrete: } \prod f_i(x)=\exp\sum\ln f_i(x)$$
to be turned into
$$\text{continuous: } \prod f(x)^{\mathrm dx}=\exp\int\ln f(x)\mathrm dx$$
(where the continuous product represents a sort of multiplicative integral)

is it possible to even do this? like extend a definition/fact?

Just define it to be that

violet wraith

but I defined the continuous product in a very similar fashion to the Riemann integral (as that is the entire motivation for doing this)

#

I don't know how to check if the definition and the fact are equivalent tho

bc with the discrete case I can prove it very easily using induction, which doesn't apply in the continuous case

you so badly want to engage but it’s just not worth it

#

but I think there is more to them than just wanting to say a lot about themselves

they aren’t lying but they don’t take any action to help themselves

and they then put the blame onto other people for why they aren’t feeling better

i think I have had times where I could empathize, where I want to sit in my misery for a little bit just so I can have the attention and pity of other people

but more recently feeling miserable is utterly horrible and I don’t want to feel like that

i think the difference is in self-loathing and lack of attention

out of all errors in our current time system, i think the most notable ones are the hour and the century

#

you wont refer to 2:00:00 as "2:60:60"

#

so referring to 0:00 as "12:00" feels like a weird decision to me

#

the 1~12 o'clock system also doesnt line up with the am/pm system

#

the cutoff point of the 1~12 o'clock system is at 1:00, but the cutoff point of the am/pm system is at 12:00

#

and there's the century

#

1701 to 1800 are known as the 18th century, which doesnt line up with our current system of second, minute, year and decade

#

the CE/BCE system is also cursed, particularly in the conversion of the two

#

2000 years before 500CE is 1501BCE

#

not 1500BCE

#

because there is no "year 0"

#

which doesnt match up with the integers

over [time period] = across [time period]

the over is not a descriptor of the time period

it's not >x where x ~ 30Y

it's just "over x as a [job], [name] [verb] ...", where x ~30Y

Hi hi, I'm new here. I just thought I'd ask a few questions.

  1. Do you do math out of interest or necessity?
  2. If you do math out of interest, what advice would you give someone who wants to be more interested in math?
little vine
#
  1. Both
  2. It only got fun for me calculus and beyond. It's hard to get excited at math below that, at least it was for me. Treat it like a game except real

personally I think you should appreciate the simple stuff, and as you learn more, what you consider simple and appreciate will eventually end up being complicated

#

but you should still appreciate the simple stuff

Don’t prove anything if you don’t want

Just partake in math you enjoy

Don’t force yourself to put up with stuff you don’t enjoy or can’t understand

As you grow more interested the desire for rigor naturally develops

Finally done my personal project! Its on proofs and we had 2 months to do it. I didnt have an understanding of proofs so a lot of research and brainbreaking went into this. Im in grade 10 so this was definitely a challenge

I was really dumb and decided to do a proof by induction as my first attempt at proofs… bad idea. The amount of brain breaking that took place

tawdry hamlet
#

I guess my biggest hurdle is not knowing where to go for resources, especially as a neurodivergent. I don't really have the patience for books, but don't know where to go for resources that have the advanced topics I want. It's like the internet stops at calculus. You want to learn past that, you have to read a book. And my brain can't focus unless there's a literal progress bar, like in ebooks, and yet I also don't want to support Jeff Bezos by getting stuff for my kindle.

#

Actually. There is a YouTube channel called "bright side of mathematics " that you might like. It's post calculus and quite good. But I think at some point you can only find complete information in books. I'm lucky in that studying from books is my preferred way to learn

#

Do you like doing problems out of books? Because that's the important part

tawdry hamlet
#

So long as I can check that I got the answer right, I guess.

little vine
#

Prioritize books where you can find solutions online in that case, also make a math stack exchange account, or ask in a relevant channel here

tawdry hamlet
#

Okay, cool. With the holidays coming up, I've got a budget for such books. Do you have any pointers of where to look?

little vine
brittle socket
#

If the book doesn't have solutions (which is common) you can try to reread your own work a couple times

#

Like perhaps after you finished chapter 1-3, you reread all your proofs you completed so far and do any necessary corrections, for example.

alpine kindle
#

and a few are the wrong way around

#

like in the first one you've gone from x+z > y+z to x > y

#

(also you've used subtraction in the proof which isn't particularly nice in the naturals)

when writing an application (personal essay portion) for a math related summer program, should i mention math in "What are your interests and hobbies"? there are other sections which ask for specifically what my mathematical experience is, so im not sure if the question is asking what my hobbies are outside of math

#

is it more asking about i.e. what sports i like, do i like to read, etc.

#

as compared to "I like pirating textbooks on the internet to study math in my free time"

#

which pretty much sums up my life

i think you should mention maths again there but not as the only thing

Otherwise it'd seem like an exaggeration i guess

How can I copy bookmarks from one pdf to another?

#

I have two versions of a pdf, one is bookmarked and the other is not. But the non-bookmarked one is of better quality, so I would jsut need to carry the bookmarks there

#

I think you can do thingsl ike that in adobe acrobat pro, but I don thave that

#

the pages do align

#

can I easily delete pages from a pdf? Like I have to delete 900+ pages. Because I merged them, if I can delete those pages Ill be done

wispy plover
#

so with jpdfbookmark you can export and load bookmarks from one pdf to another

#

This kind of solves my problem, but the thing is it cannot open the pdf of best quality I have

#

I put the bookmarks into another pdf of better quality anyway, so if I find nothing else, Ill be satisfied I think

#

like to be frank, both pdfs (not the original one, the other ones that are better, the original one with the bookmarks is pretty bad) have equal quality, but one has thicker margins, and I prefer that. But anwyay, tahnks for the recommendations 👍

#

I think it is not opening tho beacuse the pdf is from Springer

#

and maybe its protected

#

or something

#

idk, it just wont open

#

uhmm wtdym? Never heard of that

#

oh open in normal pdf reader yes, sure

#

I mean in jpdfbookmark

#

eh no

#

no

#

because I could do it with another pdf

#

which has the same number of pages

#

(perhaps tho, its heavier, idk)

#

Ok, Ill try

wispy plover
#

okay so, this is what I did, I deleted the first page (picture of the cover). The size is almost the same, but now I'm able to open it in jpdf lol

Logic or CS nerds:

#

how do we know the halting problem applies to programs in general

#

the proof to show undecidability of a program halting involves like

#

inputting the "halting decider" into itself

#

what if there is a halting decider that works for every program, except ones that involve the halting decider itself?

storm sage
#

there are certain classes of programs which you can solve the halting problem for though without a problem

#

like for example, primitive recursive stuff always halts (in pseudocode this would be like, programs that only use bounded "for" loops)

#

so you can solve the halting problem by just always outputing "Yes, it halts."

junior jolt
#

@storm sage im aware of all of that

#

what i was wondering was

#

a general program valid for all inputs, except inputs that involve the program itself

storm sage
#

I'm not sure how you would check that the input involves the program itself

#

Like, if you can make a general halting problem then you can basically solve every mathematical conjecture (collatz conjecture, goldbach conjecture, etc)

junior jolt
#

every?

#

so ur saying any mathematicla problem can be translated into a halting problem?

storm sage
#

yeah a good deal of mathematical conjectures can be framed as a membership problem

#

for example

#

the program for the goldbach conjecture would look like this:

for each even natural number n:
  check if it can be written as two odd primes
  if it can't, then halt
junior jolt
storm sage
#

I'm not sure if it's meaningful to say "any mathematical problem" can be

#

I believe you could do this for any first-order statement in arithmetic (?)

junior jolt
#

a very large class of problems can be written like that ig

storm sage
#

but you can't rule out the possibility that there is a larger number which it doesn't halt for

junior jolt
#

ye ofc

storm sage
#

so like

junior jolt
#

that doesnt address my point

storm sage
#

maybe that larger number "encodes" the halting program in some way

junior jolt
#

right

storm sage
#

like, self-reference is not often straightforward

junior jolt
#

wait i dont understand what u mean maybe

storm sage
#

but if you can find a way to prevent this outside of certain edge cases, then you've solved the conjecture basically

junior jolt
storm sage
#

right

junior jolt
#

my response is that we explicityl define any input, so we know what it includes

storm sage
#

well

#

so for the collatz conjecture, the input is natural numbers, but we know that natural numbers can be "code" for programs

#

wait I don't know where I'm going with this

junior jolt
#

lol

storm sage
#

like, for the collatz problem, does it "include" the halting decider?

junior jolt
#

or something else

storm sage
#

yeah

#

say we have a halting decider and we're inputting the collatz code into it

junior jolt
#

well it doesn't include a halting decider cuz theres no mention of it

#

maybe not the answer u were looking for but i dont see why its invalid

woven whale
#

yoyoyo

#

I ordered a comm alg and ag book

storm sage
#

okay but then how do you decide in general if it contains a mention of the halting problem? because the generalized collatz problem reduces to the halting problem, but there's no obvious mention of the halting decider inside the problem statement of the genderalized collatz problem

storm sage
woven whale
#

600 pages stare

eager reef
storm sage
#

like if you could make such a halting decider that works for every "non-pathological" problem then you've basically solved collatz

woven whale
storm sage
#

and a ton of other problems

junior jolt
#

there exists (almost) general halting decider => can decide if goldbach program halts
can decide if goldbach program halts ! => there exists almost general halting decider

eager reef
junior jolt
eager reef
#

AG will be a tough nut to crack

storm sage
#

so if you wanted to make a halting decider, you'd have to exclude this program from the list of inputs you could consider

#

but then how would you decide which programs to consider and which programs not to consider?

junior jolt
junior jolt
#

damn

halcyon turtle
storm sage
#

you can solve the halting problem for a large class of programs though

#

which is good

junior jolt
#

which ones?

#

i think you mentioned above

leaden torrent
#

consider the function isEqualTo1()

#

does this halt

junior jolt
#

lol

#

yeah

storm sage
#

anything that has only bounded for loops halts, for one

#

I'm not sure what the class of programs that you can solve the halting problem for is called

#

My knowledge in this field is pretty meager lol

#

sounds related to decidability

#

but its not quite the same thing

like how do you understand precisely which rules govern syntax in natural language? How complex are those rules?
