Christoph Schiller has updated his paper
http://arxiv.org/abs/0905.3905 . He changed the title and the abstract:
Deducing the three gauge interactions from the three Reidemeister moves.
We give one of the first known arguments for the origin of the three observed gauge groups. The argument is based on modelling nature at Planck scales as a collection of featureless strands that fluctuate in three dimensions. This approach models vacuum as untangled strands, particles as tangles of strands, and Planck units as crossing switches.
Modelling vacuum as untangled strands implies the field equations of general relativity, when applying an argument from 1995 to the thermodynamics of strands. Modelling fermions as tangles of two or more strands allows to define wave functions as time-averages of strand crossings; using an argument from 1980, this allows to deduce the Dirac equation.
When modelling fermions as tangled strands, gauge interactions appear naturally as deformation of tangle cores. The three possible types of observable core deformations are given by the three Reidemeister moves. They naturally lead to a U(1), a broken and parity-violating SU(2), and a SU(3) gauge group. The corresponding Lagrangians also appear naturally.
The model is unique, is unmodifiable, is consistent with all known data, and makes numerous testable predictions, including the absence of other interactions, of grand unification and of higher dimensions. A method for calculating coupling constants seems to appear naturally.

This appears to be one of the few approaches around that predicts a lack of GUTs, of SUSY, of usual strings, of branes, and of loops. Christoph really does it in a way that goes against the ideas of almost everybody else :-) He appears to prefer Louis Kauffman's ideas.
He now cites David Deutsch and his talk on
http://www.ted.com . Deutsch said in his last talk that truth is defined by "hard to vary" explanations. Christoph claims that his model has this property - that it is hard to vary - and thus that it could be true. Boy, if so, either this is totally wrong or it is totally true ...
