But firstly, a few words on the golden ratio. I won't go into all the detail because you can find plenty on the net, but in short it is a mathematical ratio related to the Fibonacci sequence. It pops up in nature, and it is linked to what humans perceive as aesthetically beautiful.
But it doesn't stop there. Put on your physicist hat, and you'll discover the ratio also results from objects repelling each other. Switch to your biologist hat, and you'll discover that the growing points of living creatures are driven by dividing cells moving away from each other in the most efficient way (explaining why the ratio can be seen in nature).
