What Is This Shape Called?
In the centre of a sunflower is a seed pattern similar to the shape of a galaxy seen side-on, or the sparks from a Catherine wheel firework, like the beginning of lots of rotating spirals all starting out from the same central point. Does this form have name please?

Best reference to a name that I can find is Fibonacci spirals. I doubt the pattern of a sunflower seed head, which exhibits multiple such spirals, has been given a name.

Thanks Baldric, the Fibonacci sequence and the golden ratio are more like describing the process which forms the pattern and I wondered if it had a name as such. I have a sunflower in a vase on my table at the moment and the amazing thing about it is that the pattern works simultaneously left and right handed. If I were to try to make an accurate drawing of it it would take year.
The small forecourt to my village church has this pattern laid in granite cobblestones, so I guess paviers must have a name for it.

It's a particular form of logarithmic spiral https:/
called a golden spiral.

I can recommend the book, I sent my copy on to another sceptical ABer and it seems to have altered his views somewhat - at least he never came back. :0)

'Do you think these underlying patterns in the above examples and those found in say non-Euclidean geometry have arrived there by some sort of accident'
Not accident, no....evolution. As a VERY simple example, a bee's honeycomb with its hexagonal pattern could be taken to be 'designed' whereas it is simply the strongest and most efficient shape. Seeing regular patterns in nature (Giants causeway as another simple example) could lead one to conclude the workings of a 'designer' when in fact physics is at the heart of it.

Zacs; The necessity of natural forms is true, but physics isn't at the "heart" of anything, it is purely our (arguably limited) tool for trying to understand the world in which we live. And how would it account for the reality of the Fibonacci sequence and the forms found by projective non-Euclidean geometry?
The problem at the heart of 'intelligent design' is that it offers no explanation for how an alleged 'intelligent designer' came to exist, whereas evolution clearly demonstrates the essential process necessary for the development of complex systems, some of which have inherited through natural selection the means by which intelligence arises. Such an understanding likewise relies on the development and reasoned use of ones own intelligence.
