Interesting post up at Tall Bloke's Talk Shop who reckons he can discern a Fibonacci series and the Golden Ratio in the way the solar system works – go to http://tallbloke.wordpress.com/2013/02/20/a-remarkable-discovery-all-sol… and this will be one of the themes in the upcoming conference at Leeds University.
In one of those coincidences, there is a paper on fibonacci series and the golden ratio in other areas of nature – see http://phys.org/print280548662.html
