Dear Plamen,
To begin, please allow me to apologize for joining the conversation midway
without having read your earlier postings.
It's obvious that you also expressed the sense of what I was saying. There
are about 6 fundamental laws of physics, which allows for several hundred
combinations among the laws. Meanwhile, most living systems consist of at
least 40 identifiable constituents, which can interact on some 10^47
possible ways. It should be no surprise that (many?) more than one
combination can satisfy any specification of the laws. So the laws are not
broken; they simply lose their power to *determine* a unique outcome.
As you say, sufficiently heterogeneous living system can usually find a
way around most obstacles in their way.

I should have mentioned that SOC can also possibly apply to heterogeneous
systems. For example, we have plotted the countervailing properties of
networks -- their efficient performance vs. their reliability, and we have
found that ecosystems from various habitats all achieve about the same
balance between these two traits. (See Fig. 7 on p1890 in
<http://people.clas.ufl.edu/ulan/files/Dual.pdf>.) These metrics do have
heterogeneity built into them. (They are calculated on n-dimensional
networks -- each node representing a distinct constituent.) Some have
suggested that the balance point is very near a critical point. Ergo, SOC
can apply to heterogeneous systems.

I have severe doubts about quantum gravity -- at least quantum in the
sense of Planck. (Quantum logic is another matter, and may apply to
gravity.) The Planck constant and the gravitational constant are separated
by some 43 orders of magntude. The engineering rule of thumb is that
phenomena characterized by dimensionless parameters greater than 10^5 or
less than 10^(-5) are dynamically independent.
Quantum computing, on the other hand, might prove quite helpful in
addressing the combinatorics of heterogeneous systems. Let us hope.

So then you are quite aware of the combinatorics and surprises connected
with dialogs! It's a complicated world!
Thank you for your contributions to FIS, and I apologize again for not
having read your earlier postings.
