Present day physics models reality with two theories, General Relativity,
and Quantum Theory. These work very successfully at scales, respectively,
of the very large and of the very small but the two theories remain
incompatible despite decades of work seeking to unify them. Process Physics
is a deeper theory designed to overcome the profound problems within current
physics by taking into account the fundamental limitations of logic
discovered by Godel and Chaitin. In Process Physics, the space of general
relativity and the fields of quantum theory are emergent features of a
self-organising, evolving, and competitive relational information
processing system which is characterised by dynamic fractal topological
defects described by a quantum homotopic field theory. The model is deeply
bio-logical, revealing that at all levels reality has evolved processes for

The 2000 Silver Bragg medals, awarded for achievement in the final
undergraduate year of a Physics degree, will be presented. Three
speakers, one from each SA University, will give a talk on
their research work.

"RBS Analysis of 'Quasi' Standards for Studies of Mixed Minerals"
Rutherford backscattering spectroscopy (RBS) is a surface analysis technique
based on elastic Coulomb scattering between the incident ions and the target
nuclei. RBS is generally regarded as a quantitative analysis technique for
thin film compositional analysis. All analysis techniques have strengths and
weaknesses. A few samples were chosen to act as 'standards', which challenge
aspects of the surface analysis techniques. Analysis of these standards yields
insights into the accuracy of quantitative analysis. In this talk RBS analysis
of selected semiconductor and mineral samples will be presented.

"Subatomic Physics on Supercomputers"
The Standard Model describes how quarks and gluons make up
matter such as protons and neutrons. The theory that describes how these
quarks and gluons interact is called Quantum Chromodynamics or QCD.
At high energies, quarks behave as free particles and QCD can be solved
analytically. However, at low energies quarks are bound together by gluons
and QCD can no longer be solved analytically. This presents the need for
numerical techniques such as Lattice Gauge Theories (LGT) which can
In this talk I will briefly describe the Standard Model and QCD. I will
then explain how LGT's can be implemented on supercomputers such as "Orion"
which was purchased by the lattice group here at Adelaide University solely
for this purpose.
