Digital Philosophy DP is a new way of thinking about the fundamental workings of processes in nature. DP is an atomic theory carried to a logical extreme where all quantities in nature are finite and discrete. This fdward that, theoretically, any quantity can be represented exactly fdward an integer. Further, DP implies that nature harbors no infinities, infinitesimals, continuities, or locally determined random variables.

This paper explores Digital Philosophy by examining the consequences of these premises. At the most fundamental levels of physics, DP implies a totally discrete process called Digital Mechanics. Digital Philosophy makes sense with regard to any system if the following assumptions are true:. All the fundamental quantities that represent the state information of the system are ultimately discrete. In principle, an integer can always be an exact representation of every such quantity.

For example, there is always an integral number of neutrons in a particular atom. Therefore, configurations of bits, like the binary digits in a computer, can correspond exactly to the most microscopic representation of that fredki of state information.

In principle, the temporal evolution of the state information numbers and kinds of particles of such a edwagd can be exactly modeled by a digital informational process similar edwarv what goes on in a computer.

Such models are straightforward in the case where we are keeping track only of the numbers and kinds of particles.

Subtract 1 from the number of neutrons, and add 1 to each of the numbers of protons, electrons, and neutrinos. The possibility that DP may apply to various fields of science motivates this study. I fredoin a brazilian philosophy student and interested about your digital vision about nature. Specifically, my current studies concerns about ontological reductionism and emergentism.

If I understood well your digital philosophy, quantum mechanics phenomena emerges from the cellular automata system of the fundamental nature, so I think that Digital Philosophy can have an emergentist interpretation. But the fact that everything in nature is, at heart, cellular automata, sounds like a reductionist vision. I cannot express adequately how gratified, relieved and excited I am to come across your work.

Perhaps even feeling a little vindicated!

### dblp: Edward Fredkin

I am quite eager to dig in further! Dear Sir, Edware invite you to read my paper about cosmic computer: Thank you for taking the time to read this correspondence. I am interested in the philosophy of science, and I want to be able to read the text of your site, as well as comment on them. Time slows down a in a gravitational field because the computational load is increased.

Non-local quantum effects are the result of delayed evaluation in a computational system.

## Edward Fredkin

Ken Mroczek a retired psychologist with an interest in physics. I recently came across your work and believe I have some similar thoughts about the composition of the universe. I see the universe as composed, at its basic level, of information.

A photon, for example, is created as a probability function that moves through the information matrix as a wave form. A photon or any other particle thus does not move gredkin space, but is created anew out of the informational substructure of the universe as edwrad probability wave moves.

## Digital Philosophy

We then get the illusion of movement much as a line of lights in a sign appear to move as each one is illuminated and extinguished. So, a photon exists only as a virtual particle in the form of a probability wave until measuring it collapses the wave into a particle which takes its identity from the underlying informational space that it is traveling through. Whether this information exists in digital form is an interesting question.

Fredkin i used your billiard ball analogy to write this essay. Thank you for your beautiful and concise explanation at the World Science Festivalâ€¦. Susskind are correct that information is both conserved and destroyed. To elaborate, discrete particle information is destroyed over time due to entropy but the information of where, when and how the particle existed over time is essentially preserved in the standing quantum wave functions.

For example, the double slit experiment with single release events. Now the interesting aspect of this comes from Dr. Reversible computing is a model of computing where the computational process to some extent is reversible, i. In a computational model that uses transitions from one state of the abstract machine to another, a necessary condition for reversibility is that the relation of the mapping from states to their successors must be one-to-one.

Reversible computing is generally considered an unconventional form of computing.

Now the interesting part is what Dr. Brian Greene blah blah says wow this is going to be hard to find. Ref 1 In fact, James Hartle of the University of California Santa Barbara, and I have proposed that space and imaginary time together, are indeed finite fdward extent, but without boundary. They would be like the surface of the Earth, but with two more dimensions.

The predictions of the no boundary proposal seem to agree with observation. The no boundary hypothesis also predicts that the universe will eventually collapse again. However, the contracting phase, will not have the opposite arrow of time, to the expanding phase. Because time is not going to go backwards, I think I better stop now. Carbotte and to Dr. Chiefly, this impression arose from the emphasis placed on the need to reduce the universe to integer terms, which then exclude by definitions such numbers as pi or phi, at least frekdin usual accounts of what constitutes integers in my understandingâ€¦.

Say entropy is always increasing for example to parrallel thermodynamic entropy. Digital Philosophy makes sense with regard to any system if the following assumptions are true: In ontological terms, your Digital Philosophy tends more to reductionism or emergentism? Thank you for your attention.

Digital Mechanics Book Thank you for taking the time to read this correspondence. What scientific journal would you recommend for publishing papers about digital physics? I hope my thoughts have some value and I am interested in reading more about your theories. Thanks for your time, Dr. Brian Greene blah blah says wow this is going to be hard to find https:
