New volume: A Computable Universe

March 23rd, 2013

With a foreword by Sir Roger Penrose, my new volume A Computable Universe has been published by World Scientific and the Imperial College Press after my bestseller Randomness Through Computation in 2011. A Computable Universe: Understanding and Exploring Nature as Computation, introduces the views of the pioneers in the computable universe view of the world and some of its strongest opponents (including Penrose himself).

In the context of the Alan Turing Year, the book discusses the foundations of computation in relation to nature.

  • What is computation?
  • How does nature compute?

They discuss computation in the world from a variety of perspectives, ranging from foundational concepts to pragmatic models to ontological conceptions and philosophical implications.

The volume provides a state-of-the-art collection of technical papers and non-technical essays, representing a field that assumes information and computation to be key in understanding and explaining the basic structure underpinning physical reality. It also includes a new edition, prepared by Adrian German from Indiana University Bloomington and myself, of Konrad Zuse’s “Calculating Space” (the MIT translation) fully retyped in shiny LaTeX with a few corrections and improvements to figures. A free copy of which is available here (trivia: Zuse’s name was used in the Tron: Legacy film (2010) certainly inspired by his mind blowing ideas on a digital universe).

The book also includes a panel discussion transcription on the volume topic, featuring worldwide experts including a Nobel prize in quantum mechanics, physics, cognition, computation and algorithmic complexity. In this section I asked authors (and other authors asked as well) what I thought an informed reader would ask them (including myself), sometimes leading to quite heated exchanges.

The volume is dedicated to the memory of Alan M. Turing — the inventor of universal computation, on the 100th anniversary of his birth, and is part of the Turing Centenary celebrations.
