Physical processes can be viewed as dynamic distributed processing of information performed by elementary analog processors transforming input data to output data, which can be simulated in dynamic distributed processing of digital information performed by elementary digital computational processors.

Is the Universe a Computer?
- Everyone knows that electronic computers have enormously helped the work of science. Some scientists have had a grander vision of the importance of the computer. They expect that it will change our view of science itself, of what it is that scientific theories are supposed to accomplish, and of the kinds of theories that might achieve these goals. I have never shared this vision. (Nobel Laureate Steven Weinberg)
- The universe actually is a giant quantum computer. All interactions between particles in the universe, convey not only energy but also information – in other words, particles not only collide, they compute. The universe computes its own dynamical evolution. As the computation proceeds, reality unfolds. (Seth Lloyd in Programming the Universe)
- So the thing I realized rather gradually – I must say starting about 20 years ago now that we know about computers and things – there’s a possibility of a more general basis for rules to describe nature. (Stephen Wolfram in A New Kind of Science)
- turbulent flow of slightly viscous fluids such as air and water.
Propagation of Light: Dynamic or Static
The dynamic description represents the true physics of light as dynamic wave propagation, while the static description represents fictional physics of fictional light rays equipped with a mysterious intelligence capable of minimizing travel time.
Laws of Force Balance vs Criteria of Equilibrium
A(X) = 0
dX/dt + A(X) = 0
dX = -A(X)dt
