Just run a search on: prime numbers fractal, and many interesting articles (both academic and other) will surface. Search for: zeta function fractal, and you'll find more. I'm no mathematician but it wouldn't surprise me if two very deep fields turn out to be different "manifestations" of some deeper underlying truth, and I then wonder about the possibility of a larger grand unified theory that includes both maths and physics that would have far reaching insights which would go beyond both mathematics and physics, but then I realise that perhaps I've seen too many movies :-)
