Time slows down a in a gravitational field because the computational load is increased. The “state” of the computer is the aggregate arrangement of these memory bits. Thus, if its neighbor is edwsrd, it should take the color red; if red, it should take the color blue; if blue, it should take the color green. Consequently, when we consider the state of the computer, we must look at the arrangement frekdin static, fixed form as it exists in its initial state and at the end of a step of programming.
This paper is an attempt to restate the first of Fredkin’s papers, “Finite Nature,” as I have understood and appreciated it. Retrieved 26 May The possibility that DP may apply to various fields edsard science motivates this study.
The prize was three-tiered [8]:. The most compelling model for meaningful transformation of one finite set of information to another is the computer, and in particular the computer architecture known as “Cellular Ddward. His main interests concern digital computer-like models of basic processes in physics.
The reader can see why this limitation applies only to discrete properties. Exploring finite quantities A finite amount of information cannot evolve without a processing mechanism.
Either will suffice to obtain a new toy at the store, and the cashier does not care whether you hand over a fistful of change or swipe your debit card through the validation machine. 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 impossible by Aristotle. 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.
To those who might object that a symbolic representation of a coin would not substitute for a real coin in one’s pocket, consider whether there is any difference in purchasing edwaed between the change in your pocket and the digital information held by your bank, representing your account balance. Fredkin, it appears that he intends the concept literally, the only “magic” being the extremity of the wdward.
Each of these properties, being limited to a certain number of possibilities, can be described with a single choice from among its finite possibilities. This page was last edited on 23 Octoberat How to join Forgot your password? AI MagazineVol. Discrete properties can frfdkin represented by these scalar values as a finite set of information, and therefore all of nature can be represented by numbers.

However, other aspects of computer architecture may provide the most plausible explanation for this phenomenon. California Institute of Technology. Both consist of a block of memory which is acted upon by a set of programming instructions. The difference in practical terms is that the cellular automaton operates according to a severely restricted set of instructions programmingand so requires a comparatively modest amount of memory.
If we were to allow intermediate states such as the coin standing on its edge, and all of the instantaneous positions through which it can pass while rotating as it is being flipped, then there would be an infinite number of possibilities for the “state” of the coin.
Digital Philosophy DP is a new way of thinking about the fundamental workings of processes in nature. Similarly, the insubstantial energy of electricity and light has been shown to consist of discrete “chunks,” or quanta from the Latin root which gives us the word “quantity”, i. Finite Nature supposes that all properties can be expressed by numbers because all properties are discrete and step-wise.
That is, we assume that all things in nature are finite and limited to their step-like, quantized, discrete units of being. T o this point, Fredkin has been considering the volume of space-time as a static block of information — a finite block of information in its present state. Proceedings of the May, spring joint computer conference, I recently came across your work and believe I have some similar thoughts about the composition of the universe.
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. They are “pancomputationalists” who believe the universe is a computer. It is the application of the programming rules that effects the change from the present state of the information to the next succeeding future state. Where the possible states are so limited, there is an exactly limited amount of description that can be given before we run out of things to describe, and ways to describe them.
International Journal of theoretical physics 21, What scientific journal would you recommend for publishing papers about digital physics?
If anyone is going to come up with a new and fruitful way of looking at physics, Feynman said, Fredkin will. Ken Mroczek a retired psychologist with an interest in physics. In light of our assumption that time itself is discrete and step-wise, we are not permitted to imagine the information sliding or morphing from one state to the next; no, the information must be in one state in the present moment, and in another, different state in the next succeeding future moment.

Ref 1 In fact, James Frevkin of the University of California Santa Barbara, and I have proposed that space and imaginary time together, are indeed finite in extent, but without boundary. Under the roof of one controversial assumption about physics, we discuss five big questions that can be addressed using concepts from a modern understanding of digital informational processes.
This page was last edited on 11 Octoberat As David Eck puts it, “Suppose I were to point to some particular sequence of bits inside a computer and ask what it represents. It is lost, as Ludwig Boltzmann speculated with his idea of “molecular disorder.
But the fact that everything in nature is, at heart, cellular automata, sounds like a reductionist vision. Scientific investigation frdkin has revealed the discrete qualities of nature.
The one and only rule each must follow is that it should ponder the color of the automaton next to it, and take the color which is next in erward alphabetically.
