all mathematicians, not scientists
fucking kill yourself for besmirching the good name of mathematics

all i was getting at is that you will be hard-pressed to actually finish a phd at a program where you are unhappy, regardless of how well it is ranked, and if you don't finish your degree then you may as well have not gone to the really great school at all (as was the case with me)
of course good programs produce good theses, otherwise they wouldn't be good programs

i don't see what this has to do with >>9669849

i don't understand your post. i'm 23 and on track to graduate when i'm around 26/27, which is fairly normal considering i essentially took a year off

i really wish brainlets would cut the shitposts for one fucking thread so we could have an actual conversation about grad school

>>9669552
>I read from some other anon that if my uni is not top 10-15,
that's absolute bullshit, and that's why i get so triggered by fags like the guy i was arguing with earlier
i went to a literally no-name undergrad. it is actually not even ranked by USNewsToday. i ended up getting accepted to arguably the best program in the world for a theoretical computer science phd (uchicago) with a fellowship before i decided to do math.

if what you're worried about is the ranking of your grad program, a similar maxim applies. at the end of the day, especially if your intent is to go into academia and not industry, people won't really give a shit if you graduate from Harvard if your dissertation is garbage, and people will be begging for your dick if you have a remarkable dissertation even if you're coming from a not-so-great university

at the end of the day, what's most important is that you're happy at your graduate program and that you enjoy what it is you're researching. take my experience into consideration: i left arguably the best program in my field because i was unhappy where i was and i wasn't enjoying what i was studying. i'm now at a state school which is nowhere near as "highly ranked" but i'm much happier and feel overall healthier and better about my station in life.
it will be very difficult for you to complete all the trials and tribulations of a phd if you are not healthy in both mind and body and if you are not happy where you are, so make those top priorities instead of masturbating over ranking.

>How much are you expected to know
this depends on your particular program and university but typically knowledge of undergrad topology, real analysis, abstract algebra (groups, rings, fields, not categories), and complex analysis will be assumed
since your program is in algebraic geometry and number theory, you'll be assumed to have taken at least undergraduate versions of number theory and algebraic geometry

>how can you tell if you know what youre doing, that is, if you know you can do original work
even after completing a phd many people still don't really know what they're doing and have feelings of inadequacy or insecurities about their abilities
the fact that you were accepted to the program means they believe you have the potential to succeed; the rest is up to you, but you can always confer with your professors and advisors to see what they think of your abilities and if they have any suggestions

>what hours do you spend on your own work vs time you spend doing TA duties
this is going to depend on your particular department's regulations. i spend around 8 hours per week TAing classes and i have 2 hours dedicated to office hours for my students. on a typical day, i'll probably spend between 4 and 10 hours doing work outside of class, but my schedule is highly irregular at the moment so i'm probably not the best gauge.

>how big is the department, like, how many other grad students doing what you're doing?
there are about 15 other students in my year, i think we have anywhere between 40 and 50 graduate math students total. in my specific concentration, there are two other students in my year and no more than 10 total i believe.

>how often do you travel for conferences etc?
maybe once a year. will be attending conferences more furiously once my coursework settles down and my research picks up.

math bio here is exceptional from what my colleagues tell me. you're going to want to work with Dr. Bertram, he's fucking great
undergrad analysis isn't that hard but you're going to want to make sure you're confident in your proof-based math skills, since you're applied math + stats
also your credentials look more than good enough to get accepted

on-campus housing is exceptionally safe, but it's much more expensive than you're going to want to pay
i'm living just north of campus (literally across the street to the north) and it's not bad at all, but you'll occasionally happen across a homeless person or a stray nigger
there's plenty of really great graduate housing to the east and west of campus which is exceptionally safe. i'm moving into a big house with some colleagues to the west of campus next semester. the rent will also be much cheaper (i'll be paying around 370 per month)
the south side of campus is also super safe, it's just full of undergrads who love to party late and drink heavily so be warned before moving there. there are plenty of bars and restaurants in that area and it's nice as fuck.

hope you end up applying; it's honestly really great here. just stay out of "frenchtown" and you'll be fine. crime tends to keep itself contained within the ghetto.

>actually using the shift key like a soycuck
>unironically putting spaces after your même arrows
if you want my boypussy you're going to have to work harder than that

i adopted the trip for this thread so people interested in math could ask someone in a phd program questions
instead what i get is a bunch of faggot undergrads who think they know better

>>9668676
it's pretty great. i love the weather (except the humidity during the summer) and all of my colleagues are wonderful for the most part
campus is beautiful and tallahassee isn't that bad if you stay away from niggertown north of campus
some of the faculty is kind of shit, but some of them are really really great, particularly the financial and applied divisions (though pure also has some amazing people, like Paolo Aluffi)
i'll probably end up transferring after my masters though, just because i think my interests are shifting away from what is typically researched in applied math here

>>9668678
that was the only thing mentioned in the post he (you?) replied to
please learn to be less sensitive; you'll enjoy life more

>>9668662
just in case anyone is reading along this autistic adventure:
i have one colleague who has never taken a formal proof-based mathematics class in his life; he does fluid dynamics and has never needed to; he's doing just fine in our program
i have another who never took topology or any of the advanced algebras; her focus is in PDEs and dynamical systems
and i have another who, like myself, was previously into theoretical computer science and set theory; he now does geometric topology

please don't be like this poster. mathematics is a huge and wide field with many different possible angles of attack

>>9668662
>Those courses are the bare minimum that any mathematician going to graduate school should take, and anything else should be taken on top of those courses.
nah, you're wrong and your view of mathematics is myopic
you can keep believing that if you'd like, but it just makes you sound like an undergrad
i'm a guy btw sry to disappoint

>>9668655
>lol you're the one that got all defensive
show me on the doll where i touched you

>>9668659
we're all gonna make it, anon
congrats on Berkeley, i have a colleague there and he absolutely loves it

>>9668642
>The 4 weeks in a row where I was getting nothing but rejections were pretty difficult tho..
most of us feel your pain, anon
glad it all worked out for u

>>9668611
not saying i'm smart you're just feeling insecure because of the fact that i study math and because of the way that math is performed at the graduate level
try not to do that; it's sad

>>9668613
never gave a shit about analysis until now, so i never took complex analysis nor differential anything
i took two semesters of real analysis and i don't understand how you didn't read that
i did an REU in commutative algebra
and as you can clearly see by the courses i took i was much more interested in logic and set theory than the areas you've listed

btw those courses at the graduate level are absolutely atypical of an undergraduate student and i don't understand why you feel the need to posture on an anonymous imageboard online

>>9668590
>i understand it
nah, but keep pretending that you do
meanwhile the rest of us will continue doing mathematics, and you won't

>>9668579
>nope
k opinion discarded
sorry that you can't understand that different fields operate differently

>>9668566
undergrad just barely dips your toes into the world of mathematics and prepares you for whats coming in grad school
i say this as someone who took topology, graph theory, combinatorics, automata theory, two semesters of analysis, two semesters of graduate algebra, and three semesters of graduate set theory in undergrad

is math your field? because you sound clueless about the state of modern mathematics

>>9668561
wew forgot my faggy trip

>>9668539
how so? this is very typical of graduate math programs
in that time we're doing coursework and preparing for our qualifying exams, engaging in research on the side if we have time or if we come in with a master's degree already like some of my colleagues

>>9668529
still haven't passed my quals
typically we don't choose our advisor until the end of the second year, after quals

guess i'll answer the OP
>Where did you get accepted
two nice schools for a computer science phd; attended one then left to do math at florida state university
>Where did you get denied
i got in everywhere i applied for math
got rejected at caltech, BostonU, and some other good schools for comp sci
>What're you working on
machine learning and optimization on riemannian manifolds
>How is your advisor a shitter
don't have a set advisor yet
>How often do you think about killing yourself
literally every day

>>9668513
applied math mostly focussing on machine learning and numerical optimization, though i'm trying to find some time to learn monte-carlo methods on my own since they seem cool and their areas of application are intersting

guess i'll answer the OP

>Where did you get accepted
UChicago and NYU for a CS phd
attended UChicago, then left to do math at FSU

>Where did you get denied
i got in everywhere i applied for math
got rejected at caltech, BostonU, and some other good schools for CS

>What're you working on
machine learning and optimization on riemannian manifolds

>How is your advisor a shitter
don't have a set advisor yet; my advisor at chicago was a perfect human being

>How often do you think about killing yourself
literally every day
