It is bizarre that this method of predicting prime numbers is entirely visual. The system is accumulative, but also becomes very impractical to make work as the prime numbers get higher, there is just too much to show on any diagram.
It is also difficult to see if an efficient mathematical algorithm can be developed from it that can work out primes more efficiently that existing methods, and I make no claim to this idea. In fact it seems that the method is perhaps completely non arithmetic.
The colouration of the shells in Figure 23, including prime shells, reveal shells, echo shells and power shells, hint at a sequence that is perhaps more predictable that prime shells alone, but this is beyond my remit.
The importance of prime frequencies seems to me to be in their ability to avoid each other. It is as if each prime number starts off a new numbering sequence. So higher prime frequencies could perhaps be used as carrier frequencies in radio communications to reduce interference, or processes on a computer could be threaded on prime frequencies of the processor to mitigate conflict.
For the discrete Fourier transform, prime frequencies represent groups of frequencies that belong together and resonate, so the idea of a universal window size for a Fourier transform really does appear to be a naive one. Prime frequencies will just leave you wanting more and more the more samples you get.
Overall, though, I hope you simply like the pictures and find them inspiring.
