comment The meaning of scale invariance in power law distribution
What i means is that defining $f(ax)=a^\Delta f(x)$ as scale invariant property is misleading, because the distribution function is not invariant for a generic value of $\Delta$.

Thanx for the reply. Do you have references of these analogies?

comment Scale invariance in sandpile model and forest fire model
Dear Lubos, do you mean that the phases, in the sand pile, are represented by the slopes at the different points of the sand pile?

comment Power laws and deterministic systems
Thanx. But one comment. Reviewing the H-theorem i see that is based on the Fermi golden rule, that acts at the scale of quantum mechanics. But this kind of phenomenon happens to macroscopic systems too. Am i wrong?
