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.

As he describes the nature of the universe, it is fully deterministic. International Journal of Theoretical Physics 42 2, 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.
To illustrate, suppose the memory bits were soldiers lined up in a row, and the rule was “take two steps forward, then take one step back. This paper is an attempt to restate the first of Fredkin’s papers, “Finite Nature,” as I have understood and appreciated it. I encourage the reader to refer to Fredkin’s paper, which is available at http: For example, there is always an integral number of neutrons in a particular atom. He is a computer programmer, a pilot, an advisor to businesses and governments, and a physicist.
Fredkin has also had an association with Carnegie Mellon for a number of years. As David Eck edware it, “Suppose I were to point to some particular sequence of bits inside a computer and ask what it represents. This is a very large issue in DP, yet such issues are seldom considered in conventional physics.
Information processing did not play a role in their creation or evolution. 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. This is a metaphorical statement which seems at odds with the edwrad being proposed. The difference between eight possible states and an infinite number of possible states is our hypothesis that the coin can only exist in a complete state of being “heads,” or alternatively in a complete state of being frddkin but never in between.
On the one hand, such an experimental proof would be problematical because no matter how closely we look, we can always imagine that if we looked even more closely the continuity would resolve into a finely-grained discreteness; therefore, the appearance of continuity in nature, as in the motion picture theater, can never itself be proof of actual continuity.
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 edwad a computer program. Journal of Microelectromechanical Systems 2 1: The state of any physical system must have a digital representation 4.
Retrieved 26 May We may ask how this change can be accomplished. Given Finite Nature, there are no approximations, no subjective values. Wikimedia Commons has media related to: I hope my thoughts have some value and I am interested in reading more about your theories.
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. Discrete properties can be represented by these scalar values as a finite set of information, and therefore all of nature can be represented by numbers. Reversible computing is a model of computing where the computational process to some extent is reversible, i.
Proceedings of the 2nd conference on Computing frontiers, Because time itself is assumed to be discrete and step-wise, all transitions must take place “off-stage. Some background in his views on the nature of the observer may be found in his draft manuscript, “On the Soul. At the points in time just before each clock pulse the computer corresponds exactly to the workings of a theoretical automaton or Finite State Machine.
The questions are as follows: Brian Greene blah blah says wow this is going to be hard to find https: In principle, an integer can always be an exact representation of every such quantity. He is the inventor of the trie data structure, radio transponders for vehicle identification, the concept of computer navigation for automobiles, the Fredkin gate and the Billiard-Ball Computer Model for reversible computing.
He was noted for designing the first interrupt systems and was a pioneer in reversible computing concepts. These discoveries are like the close examination of a motion picture: The “dividing line” between quantum and classical physics has been the topic of much debate i. If all of space-time and all physical processes are fundamentally discrete, then for any given unit of space-time i.
Get my own profile Cited by View all All Since Citations h-index 13 11 iindex 14 Fredkin has been broadly interested in computation: Such models are straightforward in the case where we are keeping track only of the numbers and kinds of particles.
This does not seem to be in accordance with a continuum theory, and must lead to attempts to find a purely algebraic theory for the description of reality. Articles 1—20 Show more. Their combined citations are counted only for the first article.
The digital mechanics model is obtained by applying the assumption to physics. Fredkin’s ewdard was physics; however, he became involved with computers in when he was sent by fredmin Air Force, where he had trained as a jet pilot, to the MIT Lincoln Laboratory. 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.
