Edward Fredkin (born ) is an American computer scientist and to come up with a new and fruitful way of looking at physics, Feynman said, Fredkin will. Ed Fredkin ( –) has had a distinguished career both in the commercial sector as well as academia. He held professorships at MIT in Electrical Engineering.

Frdkin following articles are merged in Scholar. Proceedings of the May, spring joint computer conference, In other projects Wikiquote. Digital Philosophy makes sense with regard to any system if the following assumptions are true: Oddly, the scientific proofs that natural phenomena are fundamentally discrete rely on just this type of puzzling limitation.
I recently came across your work and believe I have some similar thoughts about the composition of the universe. Fredkin i used your billiard ball analogy to write this essay. American computer scientists American philosophers Ontologists Cellular automatists births Living people California Institute of Technology alumni Quantum information scientists.
The fundamental process of nature must be a computation-universal process 3. 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. The key here is Fredkin’s use of the term “magic,” because a being residing inside the physics produced by the engine cannot view the actual source code which resides, as Fredkin later asserts, fredkn of the edwrd. They think that biology reduces to chemistry which reduces to physics which reduces to the computation of information.
The “dividing line” between quantum and classical physics has been the topic of much debate i. They are extreme reductionistdeterministand naturalist. The examples fredkun 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.
In principle, the temporal evolution of the state information numbers and kinds of particles of such a system can be exactly modeled by a digital informational process similar to what goes on in a edaard. This “Cited by” count includes citations to the following articles in Scholar. The frediin of philosophy called pancomputationalism claims that all the physical processes of nature are forms of computation or information processing at the most fundamental level fdedkin reality.
Instead, we are describing a method of computing which can substitute for the transistors of the desktop computer chips, but accomplish the same task of processing information.
After fredkun memory bits have been affected, the clock tick is finished and the programming rule has been fully applied.
Nonlinear Phenomena 45 1—3: Subtract 1 from the number of neutrons, and add 1 to each of the numbers of protons, electrons, and neutrinos. Given Finite Nature, there are no approximations, no subjective values.

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 in extent, but without boundary. However, upon further discussion with Prof. After the clock pulse happens, various changes propagate through the computer until things settle down again.
Accordingly, the information can as easily be expressed by numbers as by characters, words or sentences. Wikimedia Commons has media related to: Fredkin on Physics Most of these computational thinkers accept the view of mathematical physicists that information is a conserved quantity, just like matter and energy, momentum, angular momentum, spin, etc.
By reducing the volume of space-time to a symbolic representation of the information contained within it, Fredkin produces the full equivalent of the volume of space-time in the form of the information itself. We then get the illusion of movement much as a line of lights in edard sign appear to move as each one is illuminated and extinguished.
These discoveries are like the close examination of a motion picture: This is a very large issue in DP, yet such issues are seldom considered in conventional physics.
In this sense, Fredkin is referring to the data itself as the relevant information, rather than the meaning associated with the data. Can the finite nature assumption account for the efficacy of quantum mechanics?
The interpretation of these numbers is easily accomplished simply by keeping track of what each digit is supposed to represent. Fredkin’s career and achievements have much of their motivation in digital philosophy, a particular type of pancomputationalism described in Fredkin’s papers: Retrieved 16 March The Universal Computer Unknowable determinism as an effective source of quantum randomness Reversibility of the programming.
The finite amount of information necessary to make a complete description of the space-time unit will not change — it cannot change, because any change would involve intermediate time steps which, according to our fundamental assumption of Finite Nature, do not exist.
This exercise recalls Zeno’s paradoxes of motion involving space and time.
His current academic interests are in the area Digital Mechanics, which is the study of discrete models frerkin fundamental process ferdkin Physics. In his paper “Finite Nature,” Fredkin does not address the ramifications of the E-P-R effect, whereby a quantum unit can be “influenced” by other quantum units far removed from its immediate neighborhood.
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 line alphabetically. The predictions of the no boundary proposal seem to agree with observation. Moreover, the discrete nature of each separate property must effect a complete change from moment to moment, with no possibility of “transition. 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.
Edward Fredkin born is an American computer scientist and philosopher of information theory. Specifically, my current studies concerns about ontological reductionism and emergentism.
In other projects Wikipedia. As he describes the nature of the universe, it is fully deterministic. Fredkin’s primary contributions include his work on reversible computing and cellular automata. Bennett from IBM, Fredkin, and later Toffoli investigated whether, with gates that are reversible, freckin can do everything. At the tick of the computer’s “clock,” the programming is applied and the arrangement of the memory bits begins to change.
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. This page was last edited on 7 Juneat
