The Divine Proportion: Does It Have a Materialistic Explaination?

So... thus far we've established that half the things you say come to phi, don't. And of those that do, they actually approximate to phi to a greater or lesser degree (random variation is that a property of natural or designed systems?). Plus we've had explanations as to why natural forces can produce these approximations.Is there anything left to discuss?

How hard do you think it is to measure these things? A middle school kid could manage to get a decently accurate result with a measuring tape and a calculator.We're not talking complicated science here.
