Any physicists should find the following article interesting. It shows how PHI as a ratio permits superluminal (faster than light) quantum tunnelling. Essentially PHI is the only ratio where waves can converge non-destructivley and thus attain superluminal speeds.
The article is very well documented and the science is all valid. The article can be found here:
