Nature and prime numbers
Another interesting fact that I found on wikipedia and ryan mentioned in a response to Jackie's post, was the fact about cicada's that come around every 13 or 17 years as an evolutionary tactic. I found that so amazing that something in nature and evolution like that can be linked to math. I was trying to think and I bet if I researched more I could find more examples of this in nature. Does anyone know quite a bit about biology or tendencies in nature that have a distinct mathematical relationship? I was extremely interested by the cicada connection and I would love to know about more.
