interesting degree!

lol

Cornell must be shit if they allow an engineer in :P

The math program here sucks

I wouldn't be surprised

lol really

This school killed my love for pure math in a single honors analysis sequence

the first semester was sooooo bad

after that I just stuck to physics classes

when did you take analysis

freshman year

so I haven't taken math in 2 years :p

wtf

how on earth did you do that as a freshman

you're way smarter than me

:(

Cornell is #13 in the US for math btw (grad school)

Trust me it sucks

the honors analysis sequence here is a joke compared to the really well known ones at e.g. UChicago

or Berkeley or Harvard

does it not have prerequisites?

if I took the honors analysis sequence at UChicago my freshman year I probably would've come out a changed man

yeah it has pre-reqs but I did those in HS so the department was chill with it

no wonder you think Carroll is too easy...

in general the math and physics departments at Cornell are really chill about pre-reqs

wtf how did you do that in HS

if you take it and you don't fail they're cool with it

my HS math teacher didn't know what a line integral was?!?!

what is this

@obe you're a failure. I'm a failure

after calc BC/multi/ODE we were encouraged to take analysis and topology courses in the Columbia SPS program for HS students

@HDE226868 IDK if you're a failure

so it helped a lot for college

as far as preparation goes that is

I took BC as a senior

certainly didn't help me get into MIT T_T

when the hell did you take other stuff

MIT </3

how on Earth are you supposed to get in there then???

what other stuff?

algebra 1, geometry, algebra 2, trig, precalc

stat

oh

you know, high school math

stats wasn't required for us; geometry I took freshman year and algebra1/2 and trig was sophomore year-we had an honors version that combined them

I was able to skip precalc

so I went to BC instead

we had placement exams for it

@0celo7 Depends. 4.0 GPA in a magnet school going into senior year, going into my third year of physics and my seventh of science (fourth at an AP level), varsity sports, 2300+ SAT superscore and still probably a failure compared to some of my clasmates.

Actually, definitely a failure in comparison. Some of the kids at my school are geniuses. I look like an idiot in comparison.

how the fuck

Seriously.

I'm not smart

this is really sad

We all dum

Lack of a social life outside the folks I'm with during extracurriculars and some friends? Cutting down hobbies to a few but enjoying the ones I do?

::shakes head at this glimpse of the American school system::

@ACuriousMind please tell me you didn't take some shit like algebraic geometry as a freshman in college

I need someone to not be 30 IQ points above me

@0celo7 dude my roomate did that

made me feel like shit

oh go fuck yourself

just go

@ACuriousMind In all fairness, it was my choice.

i'm taking fucking linear algebra here

I was fully satisfied taking analysis and linear algebra

ANALYSIS

@0celo7 dude that's so much better

I'm fucking retarded

if I took algebraic geometry at any point in my life

I would fail miserably

let alone freshman year

I think everyone here has what you call "calculus" in school already :P

I'm looking forward to linear algebra.

I already did calculus!!!!

I'M DOING MORE CALCULUS

If I apply to MIT for grad school

and get rejected again

I will become a tumblrina

@0celo7 That sounds...really unnecessary

@ACuriousMind ODEs are just more calculus

some scools call it calc 4 ffs

@ACuriousMind Depends. Some programs (e.g. mine) spread it out so they can go into more.

What the hell do you do in ODEs if you don't know any proper analysis?

@0celo7 if it makes you feel better

You can't even prove things like Picard-Lindelöf then

I certainly didn't know any of HE when I was a senior in HS

nothing will make me feel better

You definitely know more GR than I did at your age

that does not make me feel better

@0celo7 Do you have a social life?

hell no

shit I thought I was smart

is that mary's superpartner?

Do you have friends?

thank you folks I'm here all week

leaves room

@HDE226868 yes

@FenderLesPaul lol

I was going to go out tonight, but I'm seriously upset

@0celo7 Okay, you're normal.

I didn't mean to imply that I'm friendless. I should have phrased that better.

Abnormal, yes. Total loner, no.

life is an enigma

...

Yet we have no Turing. Or even Benedict Cumberbatch to play Turing to solve the enigma.

I have lost all interest

...

Does that mean no more GR skype sessions?

Say it ain't so

what's the point

The point is you'll be the only nuclear engineer that knows why all cauchy surfaces are diffeomorphic to one another

how am I supposed to solve linear systems when I could be taking algeraic geometry

and that my friend is what it's all about

@FenderLesPaul you know Feynman was a nuke

he knew that

Feyman is smarter than me too

Feynman was smarter than everyone

that doesn't count

Feynman did not take algebraic geometry as a freshman

he was too busy getting laid

:(

you're not helping

sorry :(

do you at least know 8.1.1 yet

I can't die before knowing that

I still don't know how to fully prove it I'm afraid

"the federal government is not happy when you tell them there is no solution"

I asked some people in my group and they didn't know

did you ask Wald?

I won't get to see him until mid september or so

Do you know who Abhay Ashtekar is?

I'm going to visit Fernando, maybe he knows

I know the last name

did you ask your GR profs?

I met Ashtekar for the first time a few months ago at the Eastern Gravity meeting

he was convinced I was the guy who brought in the coffee and snacks

:(

My prof should be back from caltech in a couple of days so I'll ask him then

why do I know his last name

what did he do

He did a lot of GR stuff

and then moved on to loop quantum gravity stuff

what GR stuff did he do

mostly things on globally conserved quantities and conformal infinity in curved space-times during the 70s

he's referenced a lot in chapter 11 of Wald

that's why you might know his name

yup I see that now

the other guy that's mentioned in that chapter a lot

Jeff Winicour

serious question, how are you supposed to feel good about yourself when you didn't take algebraic geometry in freshman year

he looks like one of those bagel salesman in Manhattan

"salesman"

having never been to Manhattan, I don't know what that means

@0celo7 it doesn't bother me because I don't really care about pure math

especially not algebraic geometry

it bothers me because I'm not intellectually capable of that

I've come to peace with that

I struggle with basic analysis

ok, change that to analysis

it's one thing if I knew I'd be capable and still didn't do it

that would bother me

but if I knew I couldn't even possibly handle it as a freshman

then I make peace with it

I can't make peace with the fact that somehow every German takes analysis freshman year

Their system is just different

I really struggle with it

it's not just Germany

dude I grew up there!

Belgium for example has the same system

idk what to tell ya :p

so what German high school students don't know GR, they can still do math that I can't grasp

you'll get over it in a day

at the end of the day there's nothing you can do but keep learning anyways so don't dwell on it

When I took QFT my junior year there was a sophomore in the class

made me feel like shit for a week

then I was like "I got problem sets to do" and stopped caring

so you'll get over it :p

junior? holy crap I'm set to take QM senior year

you're missing my point lol

who cares when you take it? you're taking it to learn

take it whenever you feel capable

better to take a class when you feel totally capable so you get the most out of it

you're missing my point

than to take it really early and struggle and get very little out of it

I used to think I was a capable person, now I realize I'm not

yeah that's what college does to you

we've all been there

pats

@FenderLesPaul Good in theory, but in practice the schedule most colleges offer is the one you have to take. You can add courses and take a grad course, but only if you want five or six courses in a quarter (or semester).

@NeuroFuzzy that depends entirely on the school

my school for example has no set physics curriculum

@FenderLesPaul I can't take arbitrary classes

only a recommended one

@FenderLesPaul US?

@NeuroFuzzy yes

@FenderLesPaul Where?!?

Cornell

@FenderLesPaul Wow.

all engineering programs are strictly controlled

I appreciate the system a lot

it's leniency that is

you don't want a nuke who can't do fluids at extreme temperatures

without it I wouldn't have been able to start GR or CFT research

no way in hell a professor would take me if I hadn't taken QFT or GR

@0celo7 Oh the engineering program here is pretty rigid from what I know

the physics program is not though

but I know like 2 engineers

so idk how reliable that information is

I don't see how it could not be rigid

there are certain things on the PE exam that you have to know

-sigh- my experiences are with studying Lagrangian mechanics beforehand and being made to take the courses again, doing every problem in ch 1-4 of griffiths electrodynamics beforehand and then being made to take a course using ch. 1-4 of the same book anyways, and same with real analysis. :(

thermo, fluids, circuits

at least I have a boatload of A+es to show for it...

A+?

Well we can't skip classes

we don't get A+s

there are required classes

:(

we just have the freedom to take them whenever we want

like we can skip out of the intro QM sequence

but we can't skip out of the intermediate QM class

and we can skip out of the Purcell EM class but we can't skip Griffiths EM for example

and we can skip Kleppner mechanics but we can't skip the Goldstein/Landau mechanics class

so it really depends on how prepared you are beforehand

all the IPhO kids knew Kleppner problems like the back of their hand so they tended to take Goldstein instead

tfw using Giancoli

I get to do sig figs! yay!

(not even kidding, that's my first homework)

oh yeah that's one of those books that has crazy numbers for everything right?

like mass = 9480534865.000036 kg

no

oh

dope

@FenderLesPaul Huh. Well that's not really taking them when you're capable.

Sure it is; how is it not?

if I took intermediate QM and got an A+ and took QFT 1 and 2 and got A then I don't see a need to take intro QM

well only QFT1

QFT2 was only pass/fail

but anyways that's besides the point

I'm really starting to think a 5 year MS is not great

there's too much I'd be missing

and I still have to read the linear alg notes

there's still an SR course requirement I have to satisfy lmfao

...have I mentioned that I never need to take a course again? :D

apparently 3 GR classes doesn't cover that

stop making me sadder @ACuriousMind

@ACuriousMind how do I get into category theory?

@0celo7 By, uh, taking a course that uses it?

ain't nobody got time for that

I mean what are the prereqs

Algebra will be useful since many examples come from it, but as for category theory itself, I think it actually hasn't got any prerequisites, but it's a vast field - e.g. if you want to look at things like topoi or Grothendieck topologies or whatnot, good understanding of topology and the notion of homotopy is useful.

Dr. Freire pretty much told me I need to do algebraic topology before I can be useful

he stressed the importance of homotopy

Well, it depends on what you want to apply it to, and which part of "category theory" you want to do.

I asked him about doing fiber/re bundles and K theory.

Indeed, there is a whole chatroom devoted to homotopy theory.

whaaat

that's awesome

we could make a GR room

we should do that!

yeah we should

why haven't we done that already!

I feel better now

Dydak ranted about government budgets

he's awesome

how does one make a room

also why did people star that

@0celo7 I don't know about K-theory, but reading the nLab article indicates it is indeed full of algebraic topology and homotopy theory.

@ACuriousMind roommate is gone, Skype time?

And fiber bundles of course are topology

All the real math books on fiber bundles start with a review of homotopy

@FenderLesPaul do you have an awesome name in mind?

@0celo7 Not at home, haven't got a mic. Soonest I can offer you is Saturday, I'm afraid.

shame

@FenderLesPaul I'm making the room now, we need a name

@0celo7 yeah I'm thinkin

yo momma so fat, her ass not contractible to a point

@0celo7 how about "the black hole"?

The event horizon

oooh

what does that mean

no one will want to come in out of fear they'll die

lmfao

Norbert Straumann fan club

that reminds me

The raider end zone is called the black hole

I need to bug the librarians again

they promised to acquire the book for me

But, yeah you're right it's kinda scary

@ACuriousMind ideas?

something with manifold

maybe

The SE manifold

lame

Einstein's Dream?

sounds sexual

The space-time continuum

too pop sci

The warp drive

how's that for pop sci

no!

the wormhole warp drive black hole singularity

^

yo momma got a black hole

-_-

NO QUANTUM ALLOWED

Real space-times have curves

Wald 8.1.1 discussion

YES

done.

woo

description?

hmm, spacetime or space-time

spacetime

ok

description?

uhm

GR discussion

"General Relativity chat" seems to the point

Chat about General Relativity.

sure

GR chat

nice

I need to make a list of approved resources on GR

Good place for gaming chat too :P

with short descriptions

c'mon this can be awesome

@skullpatrol good point

@0celo7 Randomly switch between both to irritate readers.

I take it one of your classes did that?

is there any way to sticky a list to the side of the chat?

like make a google doc and link it

wow we have ODE homework

Not permanently

@ACuriousMind please pick a difficulty scale

from what to what

Skyrim - Oblivion - Morrowind

?

a 1-10 scale is bad because there's always a harder book

Choose a logarithmic one, then

1 to infinity :P

And place at 10 the hardest book you've read thus far

hardest book would probably be Wald QFT because I can't into operator algebras

at least I can pretend to into topology

actually 0 to infinity is a book

i need to make a template for these reviews

@FenderLesPaul are you good at such things

Are you still getting ba 404?

no the TA came through

For Lin alg

just finished actually

Cool

What was wrong?

@ACuriousMind is that ODE theorem you mentioned the uniqueness theorem?

if so, that just gets thrown around

@0celo7 Compared to Jamal we're all failures right?

@obe yes

did you see the new chat

It's going to be awesome

Where?

check the stars

@0celo7 I'm not good at that stuff unfortunately

@FenderLesPaul do you think it would be cool to have a resource list at least?

@0celo7 definitely

@0celo7 At my university you can take math courses without prerequisites.

docs.google.com/document/d/…

@0celo7 Yes, it's existence and uniqueness based on Lipschitz continuity

LOL that difficulty setting

@ACuriousMind I was planning on asking the prof about that. Let's see what he says.

The next class is titled "uniqueness"

Let me edit the docs.

Soo...you're gonna pull a physicist and just solve the things in that class, or what?

sorry, you have to gain a GR medal to get mod privileges

@FenderLesPaul do you want to be able to edit? I need your google account name

@ACuriousMind Huh?

pull a physicist?

@0celo7 How many answers is that?

@0celo7 is that the same as my gmail id?

not answers

hell, ACM has more GR points than I do

but then again he's smarter so :(

@FenderLesPaul maybe, let's see

wait it's not public is it??

I don't know how to do this properly 100%

@0celo7 no idea

Difficulty: let U be an open set… / 10

@0celo7 How so?
