Starting with the suggestion of Fischler and Susskind, various attempts have recently been made to apply the holographic principle to cosmology. Among these is a generalisation by Bousso which avoids the difficulties of the original proposal in the re-collapsing FLRW models. Here we take a closer look at the question of holography in cosmology with(More)
SUMMARY Traditional methods of genetic study design and analysis work well under the scenario that a handful of single nucleotide polymorphisms (SNPs) independently contribute to the risk of disease. For complex diseases, susceptibility may be determined not by a single SNP, but rather a complex interplay between SNPs. For large studies involving hundreds(More)
1: The Theme A key assumption underlying most present day physical thought is the idea that causation is bottom up all the way: particle physics underlies nuclear physics, nuclear physics underlies atomic physics, atomic physics underlies chemistry, and so on. Thus all the higher level subjects are at least in principle reducible to particle physics, which(More)
In a cosmological context, the electric and magnetic parts of the Weyl tensor, E ab and H ab , represent the locally free curvature – i.e. they are not pointwise determined by the matter fields. By performing a complete covariant decomposition of ∇cE ab and ∇cH ab , we show that the parts of the derivative of the curvature which are locally free (i.e. not(More)
Insofar as South Africa underwent a rapid transformation from apartheid to democracy, it may provide a unique laboratory for investigating aspects of revenge and forgiveness. Here we suggest that observations and data from South Africa are partially consistent with the hypotheses generated by MCullough and colleagues. At the same time, the rich range of(More)
