@0celo7 oooooh :(

0celo7

sorry

TanMath

so sad...

0537

=(

TanMath

@ACuriousMind is sad...

Sir Cumference

@0celo7 You broke his heart

TanMath

23:00

^

0celo7

@SirCumference I'm not into gingers anyway

ACuriousMind

@SirCumference My what?

TanMath

you should have lied! at least his heart would be intact...

0celo7

it never would have worked

Sir Cumference

@ACuriousMind black hole

0celo7

23:00

@ACuriousMind you have a heart in the third game

but then you SPOILER ALERT

FenderLesPaul

what the fuck is this conversation

ACuriousMind

@FenderLesPaul Not sure it's a "conversation"

Sir Cumference

@FenderLesPaul Fifty shades of ACuriousMind

HDE 226868

(Backs away into a corner looking scared)

TanMath

@FenderLesPaul watch the language mister...

0celo7

23:02

come here lil' Canadian

0537

who me?

0celo7

time for a relatively lesson

no the other one

0537

=(

0celo7

@HDE226868

HDE 226868

@0537 I'm not actually Canadian.

0celo7

23:03

lies ^

TanMath

lol

0537

@HDE226868 I know we had this discussion before.

HDE 226868

@0537 Sorry; didn't recognize you with the new avatar!

0celo7

@HDE226868 you can't read?

HDE 226868

@0celo7 I go by avatars ~2/3s of the time, in chat.

0celo7

23:04

@ACuriousMind uh, is the tensor bundle a vector bundle

HDE 226868

Besides, you're so mathy you only talk in equations.

ArtOfCode

um

leaves

0celo7

@HDE226868 what

ACuriousMind

@0celo7 Is the tensor product of vector spaces a vector space?

0537

@0celo7 burn.

TanMath

23:04

@ArtOfCode no!

have fun with my friends!

0celo7

@ACuriousMind I know that's what the problem reduces to...I want to say yes.

ACuriousMind

@0celo7 Just do it.

FenderLesPaul

I really wish I had some pie right now

TanMath

i would like to learn relativity

0celo7

Nike is suing you now, @ACuriousMind

Sir Cumference

23:05

@FenderLesPaul Click my pic

TanMath

@FenderLesPaul eat @SirCumference

ACuriousMind

wat

0celo7

@ACuriousMind Just do what? Check the vector space axioms?

I don't wannaaaaaaaa

ACuriousMind

@0celo7 Say yes.

0celo7

@ACuriousMind Because it's the right answer?

@ACuriousMind Yes, the tensors form a vector space.

Happy?

ACuriousMind

23:07

@0celo7 Uh, yes, and I don't know what you think there is to show. The tensor product of vector spaces is by definition the vector space spanned by the simple tensors.

0celo7

@ACuriousMind I don't either

Just let me be confused

FenderLesPaul

Can a silver moon touch the lantern in the sky?

I really need some food.

ACuriousMind

@FenderLesPaul What? Pass the blunt, dude

HDE 226868

The dials on the room's sense meter are redlining. Time to leave.

TanMath

@HDE226868 scaredy cat...

@FenderLesPaul eat @SirCumference

FenderLesPaul

23:10

@ACuriousMind passes out

Sir Cumference

Someone please translate this answer

-2

A: What are the differences between matter, dark matter and antimatter?

Antimatter makes not in the early universe.then the antiparticles are sub products of the asymmetry of matter,space and time.being that asymmetry between the particles antiparticles appear by the violation of cp.because the transformations of energy into mass and of mass into of energy are not co...

0celo7

@HDE226868 dei muddi macht no sense

TanMath

?

0celo7

@DanielSank

TanMath

23:12

what language is that? like latin?

0celo7

Yes.

TanMath

@0celo7 lol...

0537

lol

TanMath

i think he is going to block you...

0celo7

nooo

TanMath

23:13

anyway, thanks!

ACuriousMind

@TanMath close...

TanMath

hopefully he will come! lol

@ACuriousMind What is it then?

0celo7

@TanMath Palatinate Denglish

very very old Latin

TanMath

??????

FenderLesPaul

@0celo7 how did you know my real name?

0celo7

23:14

so alt wie dei muddi

@FenderLesPaul Venkatesh?

You told me.

TanMath

@0celo7 hahaha...

FenderLesPaul

@0celo7 Palatinate Denglish

:p

TanMath

oops...you revealed the mistake...

0celo7

what

TanMath

it isn't old latin!

0celo7

23:15

Oh!?

TanMath

because it is palatinate denglish

FenderLesPaul

mind = blown

0celo7

Very very old Latin, yea

TanMath

how can there be english in old latin?

0celo7

It's very similar to English

Celts

TanMath

23:16

must be new Latin...

0celo7

Vikings, etc.

(wonders if ACM is amused or shaking his head)

(or possibly playing a game and ignoring us)

TanMath

@FenderLesPaul your real name is Venkatesh?

@0celo7 more likely option...

ACuriousMind

::amusedly shakes his heads::

FenderLesPaul

@TanMath no it's Carl

Carl Bojangles

0celo7

@ACuriousMind headS

HE'S A MONSTER

TanMath

23:18

nobody knows on the internet whether you are saying your real name or not...

FenderLesPaul

@ACuriousMind check your multi-headed privilege

TanMath

@FenderLesPaul hello Carl!

0celo7

My name is Einstein

ACuriousMind

@FenderLesPaul wat

0537

I wish my name was a number.

TanMath

23:18

cool name!

0celo7

@FenderLesPaul dude my Am Lit class is infested with SJWs

ACuriousMind

@0celo7 Hey, that's speciesist.

FenderLesPaul

@0celo7 ugh

to be expected but ugh

you should troll the class

0celo7

@ACuriousMind idgaf ::fills flamethrower::

@FenderLesPaul we're doing pre-civil war lit

the prof made us write like one sentence explaining America

so he could give us his really smart answer

one person wrote "socially backwards"

prof was like wut

FenderLesPaul

lmfao

kids these days

0celo7

23:21

mine was the best:

TanMath

from @SirCumference's profile:

> Scientific fact: If you took all the veins from your body and laid them end to end, you would die.

lol!

rofl!

0celo7

The landmass from the Pacific to the Atlantic bounded by Canada and Mexico plus Alaska and Hawaii.

He even drew a little map of America on the board

0537

@0celo7 is it bounded by the atmosphere or extends to infinity?

FenderLesPaul

was it shaped like freedom?

0celo7

He left out Alaska and Hawaii because they're not real states

0537

23:23

does deep space need freedom?

0celo7

@FenderLesPaul yes

FenderLesPaul

murricaa

TanMath

@0celo7 now alaska and hawaii are depressed... =(

0celo7

@0537 depends

@TanMath lol that's what someone said

TanMath

like exactly the same?

0celo7

23:24

with "sad"

TanMath

oh...still pretty weird...

0537

canada would look way cooler if it had alaska.

TanMath

i can read minds of people i do not know!

@0537 boo!

0celo7

Canada should try to take Alaska then

0537

i don't think it's possible with the value of the canadian dollar right now.

user54412

23:34

If the Canadian dollar drops any more, postdocs in Canada will be getting paid the same as grad students in the US :(

0537

like ebay is useful for me right now.

0celo7

@ACuriousMind if I'm writing an answer about tensors, can I assume the reader knows what $\Gamma(TM)$ is

it's easier than saying "smooth vector fields"

ACuriousMind

@0celo7 not really

Or rather, not among physicists.

0celo7

@ACuriousMind lol I defined tensor fields as $\Gamma(\sqcup_p T^r{}_s(T_pM))$

too much?

ACuriousMind

@0celo7 Yep

0celo7

23:41

@ACuriousMind but I can say "let $\mathcal{X}(M)$ be the smooth vector fields on $M$, then a tensor field is a $C^\infty(M)$ multilinear map..."

...which restricts to the previous algebraic definition of tensor on each tangent space

ACuriousMind

@0celo7 Mmmmmh, yes

0celo7

@ACuriousMind why the mmmmmmh

Crap do I need to define "multilinear" or something?

ACuriousMind

@0celo7 Because I'd write out what "$C^\infty(M)$ multilinear" means to make sure

0celo7

sigh...I take it this is too much?

Because then I would just write "a tensor field is a tensor for which $V=\mathcal{X}(M)$ and $R=C^\infty(M)$"

ACuriousMind

@0celo7 I'm not quite sure who your target audience is, but I don't think that's the level of someone confused about abstract indices

0celo7

23:47

@ACuriousMind uh, you were confused about them :P

@ACuriousMind Alright, I'll...rethink this.

@ACuriousMind Ok, how about I reformulate the question from the PoV of someone who knows tensors via the Ricci definition

i.e. nothing about multilinear maps, just the transformation rule
