Digital Philosophy

An informational process based on reversible universal cellular automata E Fredkin Physica D: Edward Ed Fredkinborn an American physicist, computer scientist, pioneer of digital physics and advocate of digital philosophy. Wikipedia has an article about: But the fact that everything in nature is, at heart, cellular automata, sounds like a reductionist vision.

In ontological terms, your Digital Philosophy tends more to reductionism or emergentism? Two-state, reversible, universal cellular automata in three dimensions DB Miller, E Fredkin Proceedings of the 2nd conference on Computing frontiers, He is inventor of the trie data structure [2]the Fredkin gate and the Edwars Computer Eddward for reversible computing.

If this quality were continuous rather than discrete, the description would always have the flavor of an approximation, owing to the infinite possible rotations of the coin.

Digital Philosophy | A New Way of Thinking About Physics

Nevertheless, at time step 2, the same block or cell exists in a different state 2! Proceedings of the 2nd conference on Computing frontiers, We have become accustomed in mathematics and in the natural world to contemplating the infinite — a series that goes on forever without end — and its converse, the infinitesimal — a hypothetical smallness that has no minimum.


Exploring finite quantities A finite amount of information cannot evolve without a processing mechanism. On the other hand, if we allowed the rule to be applied fully, we would see a tidy row of soldiers which had neatly advanced one step. The system can’t perform the operation now. Say entropy is always increasing for example to parrallel thermodynamic entropy.

All fredkun fundamental quantities that represent the state information of the system are ultimately discrete. By using this site, you agree to the Terms of Use and Privacy Policy. Put another way, this is to say that for every volume of space-time there will be a definite and finite amount of information contained within it.

Accordingly, at any given time frwdkin 1, the block or cell exists by eedward wholly and completely in state 1. The fundamental process that we know as the physics of the natural world is an informational process. Caveat that we are not describing “particles” in the sense of atoms or electrons or anything else in the particle zoo of the Standard Model. Everything in physics and physical reality must have a digital informational representation.

A great deal of information is obviously associated with the trajectory of every particle and that information must be conserved.

How Does Nature Compute? Query whether this would satisfy those longing for something “real”? Retrieved 11 March Actually, we know little of Zeno’s preferred solution, if any, because his paradoxes come to us through Aristotle’s tracts ridiculing the frexkin themselves. The examples given from atomic theory in chemistry, and quantum theory in physics, serve as reminders that close examination can reveal step-wise, discrete properties at any and perhaps every turn.


Journal of Microelectromechanical Systems 2 1: Whether this information exists in digital form is an interesting question. As it happens, this is exactly the case with quantum mechanical transitions, or “quantum leaps,” which were anticipated by Zeno but dismissed as absurd and fredkon by Aristotle. January ” Five big questions with pretty simple answers “.

Edward Fredkin – Wikipedia

Fredkin i used your billiard ball analogy to write this essay. We do not “see” the transition, nor even the process of transition. Can the finite nature assumption account for the efficacy of quantum mechanics? How does such a transformation occur? When Fredkin invokes the concept of “information,” he is speaking of a “scalar quantity,” that is, something which is “capable of being represented by a point on a scale,” or “a quantity that has a magnitude describable by a real number and no direction.

However, upon further discussion with Prof. For example, there is always an integral number of neutrons in a particular atom.
