Continuous Computation
Introduction
Research in continuous computation (analog computation)
focuses on the theoretical similarities and differences between
it and discrete (digital) computation,
especially with regard to computational theories of intelligence
in AI and cognitive science.

This paper proves a particular field computer (a spatial
continuum-limit neural net) governed by a purely
linear integro-differential equation is computationally universal.

We present a construct, called a simulacrum, which has a similar relation
to connectionist knowledge representation as the calculus does to
symbolic knowledge representation.
