Good evening folks, quick question in case anyone knows off the top of their head: does the scalar potential for electromagnetism in 6+1 dimensions still satisfy the inhomogenous wave equation of the same form as it does in 3+1 dimensions?
 
@KevinDriscoll I'm pretty sure nobody in chat has any background in extra-dimensional physics.
 
@BrandonEnright nuh uh

Q: Maxwell in multiple dimensions: What happens to curl?

ManishearthI read this answer a while ago, and while thinking about $\nabla$, I realized something. Since the cross product can be written as a determinant, in higher dimensions we require extra vector inputs. IIRC it's called the "wedge product" in higher dimensions. Alright, how does this work when we ge...

 
@ManishEarth That's news to me :-)

@ManishEarth I saw that answer but it seemed to only talk about the fields. I'm not even sure if the scalar/vector potentials even exist in the same way. (I imagine we have to turn the vector potential into some kind of antisymmetric tensor)
 
@KevinDriscoll I know, the answer was to tell Brandon that there are people here (not me) who are good with Maxwell's equations in higher dimensions
 
@ManishEarth Ah okay. I understand.
@BrandonEnright I don't do extra-dimensional physics either, but I'm working on a QM problem with 2 particles, so a 6D helmholtz-type PDE. I Think there may be an EM analogue in temrs of the scalar potential in frequency space, but itd have to be in 6+1 dimensions for the operators to be the same.

@ManishEarth I missed this reference earlier when talking about python modules:

@Arafat As in Physics Graduate Record Exam?

Guys, the final of the luge is now.
 
Still no interest in Olympics

:D
 
There's a guy going down now who is called The Cannibal.
 
Is that his actual name, or is it a stage name?
 
That's his luge name.
And now luge Wunderkind Felix Loch. Gold!

I don't get 101
Nvm
