Yeah, I remember learning about how the Fibonacci sequence is everywhere in nature. Such a simple concept that explodes into nearly infinite complexity. And it seems to "drive" so much natural phenomena. Interestingly around that time a family friend who was a physicist at Cal Tech knowing I was of a philosophical mind asked me if the Fibonacci sequence "exists". In other words, how do you classify the reality of the sequence? A part of nature? A "law" of nature. Something we impose on nature in order to understand it ourselves , existing only due to our need to classify and categorize? Something else?
Next thing I know I'm reading Godel, Escher and Bach... Then Wittgenstein, Searle, Austin...
So... Each thing you learn creates new branches of exploration. Kind of like a Fibonacci sequence...
