ABSTRACT

Richard P. Feynman loved computation. He loved every aspect of it: Algorithms, computing machines, abstract theories about computations, and all. Uncertainty lay in the classical view – and it was quantum theory that actually showed why things could be depended on. In contrast, consider what happens in quantum theory, where each electron level remains unchanged until there occurs a transition jump. Ed Fredkin pursued the idea that information must be finite in density. Imagine a crystalline space-time world of separate "cells" in which each volume of space contains only a finite amount of information. Most theories in psychology were designed to support deterministic schemes, but those theories were usually too weak to explain enough of what happens in brains. The idea of a field abandons long range forces, and only asks the vacuum to constrain some local quantity – for example, by a differential equation.
