A duck walks into a bar. Animal control is promptly called and the duck is released into a near by park.

comment Gabriele Veneziano, strong nuclear force and beta-function
I didn't want to say it at first, but now I find it funny that it's still there after the edits of the very same expression: There is an unmotivated $x$ in the Gamma function.

comment Reference request for the terminology and usage of different types of plasmas
Thanks for the paper, I'll check it out. I have the Fridman book, although it doesn't necessarily make things clear to me yet.

comment What are the frameworks of physics?
@AlexBobrick: But by this definition, the phenomenological laws, which are experimentally accessible are more fundamental. On the other side, statistical mechanics is a way to thermodynamics.

comment What are the frameworks of physics?
I like the "more is different" paper, but I never really understood it. To me it seems as if these "entirely new laws" should be obtainable be the right renormalization from the deeper theory to the other. Phenomena are emerging, but you can see them coming from the more detailed theory. Of course, nobody can learn everything and so it's certainly a field of its own - its "not just application" only in the practical sense, because of that.

comment Some questions on observables in QM
@RonMaimon: Why do you ask? Did I make statements about what's more non-classical or more counterintuitive? I wasn't even talking about QM here in particular. I was using the spin observable as an example for something which is described by group theory and was asking why he says they would necessarily follow to exist in nature. His statement seems to imply all possible realizations would have to be present in nature.

comment Newton's Law of Gravitation, Gauss Law and GR
What do you understand by Gauss law here? The classical field from a source $\rho(r)$ are given by linearly summing over the point fields $F_{tot}(r)=-G\int_Vdy\rho(y)/(r-y)^2$. Gauss law as I understand it here is the divergence form of that. You derived the familiar radial equation (no corrections?), starting from a radial equation from the GR metric for one point mass as input. However, collecting point masses in GR and compute a metric via the nonlinear Einstein equations will not, I assume, give a metric, whose trajectories correspond to divergence free forces outside of some volume.
