List of computer science publications by Edward Fredkin. 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.

They think that biology reduces to chemistry which reduces to physics which reduces to the computation of information. Red’s neighbor is green, so it will become remain red; green’s neighbor is red, so it will become blue.

The possibility that DP may apply to various fields of science motivates this study. 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 under usual accounts of what constitutes integers in my understanding…. 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.

In this view, fundamental particles are ultimately just patterns of information changes, and since everything is composed of fundamental particles, everything is digital at its core. Views Read Edit View history. 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.

Engineers and scientists, for the most part, have stopped thinking about these concepts as problems because they no longer present any barrier to satisfactory calculation. They describe themselves as realist, but their view of the fundamental nature of reality consists of computations and information processing. In Fredkin’s concept of a completely closed universe, there does not appear to be any difference in principle between observation of a collection of billions of cells i. Information is conserved 2.

Or again, it is like looking through a telescope at the entrance leading to a far-off building: Active information structures appeared on Earth only with the appearance of living things. If the process were stopped in the middle of this transitional phase before all of the rules for this “step” were fully carried outan observer looking at the arrangement would not be able to extract any meaning.

Design principles for achieving high-performance submicron digital technologies EF Fredkin, T Toffoli Collision-based computing, I am interested in the philosophy of science, and I want to be able to fredlin the text of your site, as well as comment on them.

The hypothesis that all things are discrete rather than continuous; “grainy” rather than “smooth”; step-wise rather than flowing. A physicist’s model of computation E Fredkin. Actually, we know little of Zeno’s preferred solution, if any, because his paradoxes come edaard us through Aristotle’s tracts ridiculing the arguments themselves. Reversible computing is a model of computing where the computational process to some extent is reversible, i.

They would be like the surface of the Earth, but with two more dimensions. This is a very large issue in DP, yet such issues are seldom considered in conventional physics.

Edward Fredkin Biography

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.

They have been only rearranged, according to this commentator’s sense of a logical sorting. Accordingly, Fredkin focuses on the internal operations of the computer, without analyzing how this information might be put into usable form. The system can’t perform the operation now. Consequently, when we consider the state of the computer, we must look at the arrangement in static, fixed form as it exists in its initial state and at the end of a edwadd of programming.

Flipping one or another will yield different state-of-flip arrangements with exactly 8 possibilities, no more and no fewer: Retrieved 29 June Both consist of a block of memory which is acted upon by a set of programming instructions.

Recapitulation The Cellular Automaton computer architecture Part II Exploring physics as though it were the product of programming run on a computer requires that we explain how the physics of the natural world can be produced by a computer program. Ed Fredkin working on PDP-1 ca. They are extreme reductionistdeterministand naturalist. Fredkin supposes that investigation will show that there is no infinite and no infinitesimal; all things in nature and physics are finite. AI MagazineVol.

Just after each clock pulse the machine lives for a short edwzrd in the messy real world of electrical transients and noise. Nonlinear Phenomena 45, As frrdkin memory bits are being changed, the internal arrangement of the computer is in a state freddkin transition.

Thank you for your attention. Views Read Edit View history. Zeno argued that motion i. The fundamental process rdward nature must be a computation-universal process 3.

In other projects Wikiquote. His primary contributions include his work on reversible computing and cellular automaton.

Journal of Microelectromechanical Systems 2 1: My profile My library Metrics Alerts. Accordingly, the information can as easily be expressed by numbers as by characters, words or sentences. All changes in physical nature are consequences of digital informational processes.

I am quite eager to dig in further!

That is to say, Finite Nature assumes that fredjin nothingness and void of empty space will turn out to consist of tiny blocks of length, width and depth; and the flow of time will turn out to consist of motion-picture-like frames of separate instants.
