A proposal that computing is not merely a form of engineering but a scientific domain on a
par with the physical, life, and social sciences. Computing is not simply about hardware or …

This paper explores the idea that the universe is a virtual reality created by information
processing, and relates this strange idea to the findings of modern physics about the …

This chapter asks if a virtual space-time could appear to those within it as our space-time
does to us. A processing grid network is proposed to underlie not just matter and energy, but …

Cellular Automata have their roots in von Neumann's research on self-reproduction, but
since their debut they have been used for a much wider variety of purposes. In recent years …

Quantum dynamics can be regarded as a generalization of classical finite-state dynamics.
This is a familiar viewpoint for workers in quantum computation, which encompasses …

We define, as local quantities, the least energy and momentum allowed by quantum
mechanics and special relativity for physical realizations of some classical lattice dynamics …

The concept of emergence is a powerful way to explain very complex behavior by simple
underlying rules. Existing approaches to producing emergent collective behavior have many …

The scope of Platonism is extended by introducing the concept of a “Platonic computer”
which is incorporated in metacomputics. The theoretical framework of metacomputics …

A model representing a grid of circular counters maintaining mutual fault-tolerant
synchronization by a distributed operational rule is considered. The importance of this model …

The concept of emergence is a powerful concept to explain very complex behaviour by
simple underling rules. Existing approaches of producing emergent collective behaviour …
