I guess it isn't necessary to the spirit of the problem to require this, but it seems sensible. | |
May 22, 2010 at 14:30 | comment | added | Henry Segerman | Apart from the first few in your example sequence, you're picking out one of the spirals for which consecutive terms differ by a particular Fibonacci number (in this case 21). In the 2D version, these spirals are apparent only for a small range of radii, before larger Fibonacci number differences show up in neighbouring points. So presumably in 3D there would have to be many different sea-shells with different "angles" (rates of growth, corresponding to the increasing Fibonacci number differences). | |
