using jacobians seems gainlessly tedious

why not just split the domain up?

But that's what I did.

But one has to justify the cancellation properly.

writing something as simple as $\int_{A\cup-A}f=\int_Af+\int_{-A}f=\int_Af+\int_A-f=0$ should not be that complicated imo

Well, I wrote it out simple and with words, and added the more rigorous proof.

Evening, folks

hey

Da physicist is in town.

@pedro Indeed! And very much scratching my head over all this differential-forms business

The banana is in town.

Maxwell's Equations in 6+1 dimensions......... ugh not clear

@KevinDriscoll Cool, you studying multivar calc?

I don't think I'd call differential forms multivar calc

@Pedro Nope, just trying ot figure out if the electromagnetic scalar potential still satisfies the inhomogenous wave equations in 6+1 dimensions

turns out though that for n>4 dimensions, everyone writes Maxwell's equations using the language of differential forms

hey guys would anyone be willing to check out my question. math.stackexchange.com/questions/668993/… Thanks.

@mike I checked out the gre site. Am I right that the general test is computer based and the subject test is paper based?

yes the general test is computer based. i took it yesterday

not sure about the subject test

@JasperLoy That's correct. And the generla test you can take whenever (at one of their test centers), but the subject has specific dates.

i got a 319 on my general gre is that a good score?

you can look up percentile ranking

I guess I will take the gre in Sep/Oct of Year X and send in the applications in Nov/Dec of Year X for admission in the autumn of Year X+1.

if you're applying for math programs, what you got in quant matters more than anything else

a 165/170

that's good

wait 165/reading 170/quant?

oh no

oh

165 math and 154 reading

165 out of 170

yeah you should be fine with that math score

I think the test is stupid, but it is the only test there is.

Really @Mike ? Thats seems to be 91st percentile. I feel like I remember that our physics department prefers you are in the 95%+

OH pffffffffff

nevermind fuck me

they only require a 155 here

I am afraid I won't do too well in the test...

so i should retake it then?

No you'll be fine I think

my expectations are CLEARLY way off

I think I will just do my best and take each test once.

What's that test?

GRE general test and subject test.

@JasperLoy For me it was just an exercise in staying calm and reading the questions carefully. They were not conceptually complex.

@KevinDriscoll Yeah, those numbers are fine. 155 is a bit low but 165 would pass any cutoff.

@KevinDriscoll I hated the general because it would often give mathematically nonsense questions. I distinctly remember one that was like "What's the next term in this sequence?"

Oh

psychotechnic questions

@Mike I got a 790 (old score) on the quantitative part of the general GRE and some of my physics classmates make fun of me for it. They all got 800, of course.

oh the gre quant is complete stupid

@mike I have gotten rid of my 112 books finally, don't be mad...

@Mike yeah I'm not sure how they justify that kind of thing given that the answer could really be anything if you're given only the first few elements

@JasperLoy Did you not donate them?

@Mike Yeah I mean people who entered PhD studies the same year as me

Yeah I realized.

@Mike No, I did not donate them...

@JasperLoy Feel bad.

@Mike Thanks, lol.

Haha ya its all very tounge-in-cheek

I really wanted ot get >800 on the physics subject test but I only managed 750

I did pretty well on the math test, but I missed a couple easy mistakes

You mean made.

Yes

The GRE site is very confusing.

I took a long time to figure out what I needed to.

@mike Do your lecturers give you lecture notes for most of the classes?

@JasperLoy No.

This question is super odd. Especially the answer the teacher gave to it...

I trust you all are familliar with characteristic functions, right?

Sure

Nevermind. I misread it. Need more sleep I guess...

So it's not odd at all?

Nah, I just skipped a simple note

That made it the easiest question on earth..

It terrifies me it might happen on the test..

@Singh In your time zone, no doubt.

> Here's Looking at Euclid

^^ Best title ever?

@mick What about it is confusing to you?

Probably you need a little ring/field theory to understand that.

@anon HAI

hai

wuzz poppin'

saw movie with family

meh

which one?

lone survivor

what about?

wondering if left units automatically right units in group algebras

that's what the movie was about?

your family must've been thrilled

@PedroTamaroff operation red wings in afghanistan

haha

oh that movie?

the trailer looked terrible

the movie was good

i'm watching the departed

damn good movie

so many good actors

seemed like another generic oorah support our troops movie we get twenty of in a year

departed is one of my favorite movies

LOL scene at porn cinema

nicholson is hilarious

it also annoyed me they had the gall to use "heroes" for the trailer soundtrack considering it's ironic and not at all supporting killing the shit out of people

of course i still have not seen the movie, so

good movies i've seen this week: lego movie, les miserables, thor II

i'm surprised that lego movie is apparently good

the lego movie is hilarious... kid movies have so many gags from grown ups.

specially funny for lego fans

there are... lego in-jokes?

aha

fantabolous

one of the characters is a piece I used to own

hehehehehe

as I understand it americans were positioned to take out a taliban leader. the op was compromised in the very begining when some goat herders stumbled upon them hiding. there was a debate about whether to kill them, tie them up, or let them go (two of the three were children). they decided to let them go, which lead to them getting their asses handed to them a bit later with gunmen all over.

one guy survives, and gets saved by villagers (while one of the children they let go were tali, the other one and the old man were civilians, and their tribe was then honor-bound to help the americans).

/spoilers

that's a much better story than the trailer told

UGH 0 upvote accept

which mostly implied the second paragraph was gonna be shooting them all

@PedroTamaroff OP can't upvote, look at his numbers

reputation

it's funny he's spongebob square pants

@Mike any movie you like?

i hate all films

that's almost like hating all music

i do that too

what about 12 angry men

come on.

pedro can attest

what about audrey hepburn

i don't actually like a whole lot of older movies

12 angry is an oldie goodie. where'd you come across it pedro?

my favorite movie from last year was the place beyond the pines

ryan gosling bats eyes

a friend of mine recommended it... I watched it twice in a day

haha. pines was one movie I wanted to see but didn't.

that movie is just pure wonder

has anyone watched "el angel exterminador"?

I don't know what's it called in english

let me google

I have watched very few nonenglish films, and that is not one I've heard of

@anon i strongly suggest it. don't look up the plot or anything. it's one of those things you want to experience w/o knowing the plot

this year's oscar season was kind of ass

@anon Here

I already know it involves a bank heist and some father caught between a rock and a hard place and beyond the pines is his bolthole or something. just from my memory of the trailer.

that's fine, trailer said just the right amount

just don't go readin' a plot summary

seen The Room?

fortunately no

haha. it should be in textbooks on the theory of film, if that exists.

@anon doesn't ring Abel

of course that exists

film theory's a discipline :p

anyone seen the tree of life

wierd movie

have you seen holy mountain

nopew

lol

do it

surrealist movie

dope

literally

=D

well the exterminating angel is also surrealist

it is mentioned by owen wilson in "midnight in paris"

when he actually meets Buñuel, the director, and suggests the plot

and Buñuel is "dafaq are you saying"

i do not take owen wilson as a good source for film advice

it is just a gag in woody's allen film

no biggie

woody's allen film?

yeah

midnight in paris

stars owen wilson,

it's "woody allen's film"

anyone watched the skin I live in?

LOL

sorry about that

u should be

im watching the movie so half me brainz is on the other screen

you should watch there will be blood

i watched it man

didn't you tell me to?

its funny how the title ends up being true

heh

i probably did, i love that movie

you should watch 12 angry men

as reciprocication

is that even a word?

i've seen it

it's fun

i actually was in a stage version of that

you saw it?

nice

it was terrible, I feel bad for anyone who paid money to see us forget our lines

OH

you acted?

that's fucking awesome

i did a bunch of acting in high school

that's cool

my best role was as a retarded kid in the depression

hahaha

WAT

i died in the end of it

tell me you didn't go full retard

dayum

drowned

you went full retard and died

see

dayum

yep

what character were you?

the retarded one

what's the name?

buddy

have you read any play during school?

an inspector calls is a good one

not during school, but i've read plays, yes

my favorite play of all time is waiting for godot

don't know that one
