Looking up the definition of a cellular automata at cafaq.com, I find the automaton is defined on an

An interesting observation about some mathematical laws of physics is that they capture aspects of a

Feynman Gate The Billiard Ball Model (BBM) is a Newtonian model of computation where hypothetically

There are many different kinds of models. Given 2 systems s1 and s2, we can say that s2 is a model of

CMU with Ed Fredkin. There has been discussion about releasing some of that work as an open source project. It's preliminary right now but perhaps we could move it along faster with
