I just noticed a Feynman diagram in PSE's logo.
 
[Division by zero] We have shown that there does not exists nontrivial associative algebras that allow zero divisors and zero inverses, with with zero inverse being the zero divisor. We don't know how it happens except that at least one associative law will break as the result shows
 
@SwapnilDas what?
It's a Mexican hat potential, where's the Feynman diagram?
 
The case for associative algebras where 0 is not the inverse of a zero divisor is not ruled out yet, and will be continued tomorrow
 
@ACuriousMind There's something behind..
 
@SwapnilDas Oh, you mean not in the logo, but behind the "PHYSICS" in the bar at the top of the site.

See behind "PHYSICS" @ACuriousMind
@ACuriousMind Oh yes, I meant that.
 
sorry typo, there's one more case not checked yet
 
Ooh, I turned 16.

@SwapnilDas Happy birthday!
 
 
1 hour later…

This has got to have a suitable duplicate somewhere on the site but I can't really find anything.

So anyway
2D Alcubierre has divergent vacuum energy
But what about 2D Krasnikov???
Let's investigate
Hopefully it won't be too hard if I pick the simplest case
Since then it's just an ODE to solve
Or wait
No it's not
Nooooooo
Oh bother
Well 2D linear PDE should still be doable, hopefully
Wait
2D spacetime
There might be a change of coordinate that brings it as a conformal metric to minkowski
First I need to find the courage inside myself to move my ass and get my pen and paper
 
10:24 PM
Uh, @Slereah, isn't gravity trivial in 2D?
 
It's independant of the matter content
You can still have weird metrics
The analysis is the backreaction, not the matter field
 
10:37 PM
folks seen this one?
↑ is awesome
↑ should watch
↑ seriously

11:45 PM
anyone around?
 
hello =)
 
@Sanya, hi
 
it has been rather quiet here for most of the evening though
probably everyone's in pre-christmas stress
 
"pre-christmas stress" =/ 'tis the season to be jolly; i think they need to change the song.
 
What is this "pre-christmas stress" you speak of?
 
11:53 PM
Maybe he is Santa
 
meeting people for christmas parties, buying presents, driving kids to the christmas parties of their school, their kindergarden, their sports club, their music classes, going to the company christmas parties, ....
things like that :o
 
The thing I look forward to is the new year
That's when I get drunk and throw around explosives
 
@Sanya parties are fun, not stress; presents get bought on the 23rd; got no kids - I don't see what all the fuzz is about ;)
