In this fascinating journey to the edge of science, Vidal takes on big philosophical questions:
Does our universe have a beginning and an end or is it cyclic? Are we alone in the …

Hypercomputation is a relatively new theory of computation that is about computing methods
and devices that transcend the so-called Church-Turing thesis. This book will provide a …

to define the scope and address the central questions of an original research program. It is …

The aims of this chapter are to review some aspects of determinism that are familiar to
physicists but are little discussed in the philosophical literature and to show how these …

Are there 'biologically computing agents' capable to compute Turing uncomputable
functions? It is perhaps tempting to dismiss this question with a negative answer. Quite the …
