Wow, that's difficult. Aside from the many videos which show just cool stuff like new robots, I'm usually into the how tech affects people or how peoples needs influence tech kind of videos. The socio-thenological ones.
Other than that, I really like this one, because the guy is truly more enthusiastic and behind his ideas than other TED speakers

You have an interesting perception of metaphysics...

I'd like to know what you think it is about.

k, I'll grab something to eat - if you're still on this topic and come up with another question i'll answer is in about 2 hours

mhm, you got me confused about the conditions for stokes theorem now..

let T^2 be the flat torus of length 1cm·1cm, then the metric is g=diag(1,1) and thus the volume form is det(g)dx^dy=dx^dy=d(x·dy)=dVol

clearly int_M d(x·dy)=1 as is has to be since the Torus has an area of 1cm^2.

I conclude that it can't be stated that

Int_M dv = 0

on a compact manifold.

There must be some conditions (maybe they are so that there are just so few possible admissible vector fields)

As a theoretical physicist in my 5th year, I'm barely able to read the question. What do you expect from /sci/?
When it comes to pre 3th year collage mathematics, there is no other algebraically closed field than the algebraically closed extention of R.
