@Jasper Shouldn't you use "a" instead of "the" in that sentence? :P

Jasper

@Blue I used 'the' there because I am the most famous one in SE chat rooms.

@Jasper Then you should have used quotation marks.

@Blue why not?

Anonymous

@0ßelö7 Because SE is not a standard short-form. (You won't find that the full form of SE is Stack Exchange via googling...at least not directly)

0ßelö7

@Blue it's acceptable by local grammatical rules

Completely standard in this context

@0ßelö7 Then even doubt is acceptable by local grammar rules. ;)

@0ßelö7 BTW I think "grammatical rules" is not correct English.

@Blue why not

@Blue it is and I say it all the time

this question is killing mw

I was told by textbook r is position vector

A: Angular momentum conservation under Galileo transformation

The thing is that you are mixing two things. On the one hand, if you move your origin, all positions obviously suffer the transformation $x_{new}=x_{old}+x_{OO'}$ (and so on). But, on the other hand, the radius angular momentum $L$ is NOT the position of the particle, but its position with resp...

my brain is burnning

I know the "extra" toque is not a real toque, since R is fixed

but the new toque is nevertheless something non-zero

Would anyone be kind enough to give me a helping hand?

@ACuriousMind since when do you take back things?

@vzn meemee, that's how it's pronounced

@Avantgarde so are you studying physics?

man this rap thing is so complex o_O jezebel.com/the-making-and-unmaking-of-iggy-azalea-1797030869

Avantgarde

yeah

Azalea? Man, seriously?

bad bad bad music

Balarka Sen

lol

Avantgarde

@BalarkaSen You like standup comedy?

Balarka Sen

nope lol

9:52 PM

i don't really like many comedians

with the one exception of ze Tom Lehrer

Avantgarde

alrighty

vzn

@Avantgarde enjoyed the extremely erudite/ intellectual deconstruction/ post mortem... just dont see how anyone who did something like that Big Booty song/ video with JLo deserves such painful obscurity... o_O

Avantgarde

haha

vzn

@Avantgarde so what do you want to do with/ in physics?

Balarka Sen

xxxtentacle is still the best rapper though

XXXTENTACION IS THE GREATEST RAPPER

@vzn Whatever catches my interest

The song with Grande is the one I've heard that had Azalea on it

never mind, don't look it up.

vzn

@Avantgarde :) like that song! got one less problem without you (mentioned in article)

Avantgarde

@vzn What kinds of music are you generally into?

vzn

@Avantgarde oh, like pretty diverse stuff. not too restrictive. avoid country but can even see some redeeming qualities in it. eg kei$ha "timber"... (nice harmonica!) :) so do you have any idea what you want to do after graduation?

Avantgarde

@vzn Ke$ha... :(. Getting a job in academia. You do physics as well? I haven't seen you around here too much, I think.

vzn

@Avantgarde come and go have been pretty busy otherwise. also dont always see a lot of physics conversations. physics is a hobby/ avocation for me. what music are you into? ... reminds me, gonna go see a led zeppelin cover band "get the led out" next thursday... =D

Avantgarde

10:13 PM

@vzn I see, that's good. Hopefully SE has helped there. My music spectrum is spread out too. Metal forms a large chunk of it. Have fun at the show!

vzn

10:25 PM

@Avantgarde lol meant there are not always a lot of physics conversations in this room :| ... but yeah it can fill a void sometimes, or other times make it feel bigger o_O ... thx hope you can see some great live music too, its great in the summer around here :)

@BalarkaSen Suppose I have a bounded domain $\Omega\subset \Bbb R^n$ and a sequence $(x_n)\subset\Omega$ such that $x_n\to x\in \partial\Omega$. There exists a $C^1$ curve $\gamma\subset\Omega$ such that $\gamma(1-1/n)=x_n$, and $\gamma(t)\to x$ as $t\uparrow 1$, right?

I can draw a picture of it, but actually writing down the construction seems hard.

Q: Why do we not realize that light has mass

I'm sitting here watching waves on the lake, if there were no water there would be no waves -- if light had no mass there would be no waves, the belief that light doesn't have mass is wrong. If light had no mass the speed would be infinite but it is not, it really doesn't take a genius to see tha...
