Computing systems are everywhere today. Even the brain is thought to be a sort of
computing system. But what does it mean to say that a given organ or system computes …

It is my great pleasure to write this preface for Dr. Nir Fresco's book “Physical Computation
and Cognitive Science” based on his doctoral thesis “Concrete Digital Computation …

In The Physical Signature of Computation, Neal Anderson and Gualtiero Piccinini articulate
and defend the robust map** account--the most systematic, rigorous, and comprehensive …

The semantic view of computation is the claim that semantic properties play an essential role
in the individuation of physical computing systems such as laptops and brains. The main …

I explore the conceptual foundations of Alan Turing's analysis of computability, which still
dominates thinking about computability today. I argue that Turing's account represents a last …

The central claim of computationalism is generally taken to be that the brain is a computer,
and that any computer implementing the appropriate program would ipso facto have a mind …

Computing is a high-level process of a physical system. Recent interest in non-standard
computing systems, including quantum and biological computers, has brought this physical …

Computation is a physical process, inevitably utilizing physical degrees of freedom.
Computation, therefore, is restricted by the laws of physics and also by the construction …

This paper challenges two orthodox theses:(a) that computational processes must be
algorithmic; and (b) that all computed functions must be Turing-computable. Section 2 …

More than a speculative technology, quantum computing seems to challenge our most basic
intuitions about how the physical world should behave. In this thesis I show that, while some …
