But let's keep this local.


Question from Yon re: the most important texts for the ideas of information physics. Got me floored. Let's look at where they might be in the great informational landscape: 

  * Cahill's group in South Australia (see  [[Process Physics]] )
  * Ed Fredkin's (unpublished and incomplete) book
  * Wolfram's A New Kind of Science (WANKS)
  * all sorts of other wacky types



What are the papers that get me excited? 


  * Takesue and Hattori, "Additive conserved quantities in discrete-time lattice dynamical systems" Physica D 1991, vol 49 pp295--322. Because it gets at a proper physical problem - conserved quantities - and analyses this in (admittedly 1D) cellular automata.
  * Damasio. Somehow I read from his book "The feeling of being" as well as from a few Dennett parts, that perception (an informational process) is based around the understanding of physics: an evolved perceptual machine that "understands" better gets on better.
  * Cahill: I couldn't get my head around the paper I tried to read - prhaps there are some new things of interest, I should check the site again.
  * David Chalmers (another bloody Adelaidian, dammit, they're everywhere!) seems to have similar ideas around perception and information (see below). But I do not kno what to recommend to read.
  * The people who want to claim that there is a global background reference frame. People like Hartwig Thim (no url) or the quantum vacuum people, see e.g. http://groups.yahoo.com/group/InfoPhysics/message/59 for a copy of an article covering some ideas. Pop science, I know, but there are some rather less intelligible versions of this thesis floating around at the moment, too.
	
So we have some strange mixture of [[Quantum Physics]], perception, evolution, [[Cellular Automata]] theory and other abstract nonsenses. Hurrah! as Sir Alexander Davies would say.

David Chalmers: "Wherever we find conscious experience, it exists as one aspect of an information state, the other aspect of which is embedded in a physical process in the brain.... The laws of physics might ultimately be cast in informational terms, in which case we would have a satisfying congruence between the constructs in both physical and psychophysical laws. ``The Puzzle of Conscious Experience'' 1999 ([[Category Consciousness]])
