The Fourier Transform of the "signal" given by the number of primes
contained in the successive intervals of equal length l=216
=65536 up to N=238 ~ 2.749 x 1011 was performed.
It turns out that the power spectrum displays the 1/fbeta
behaviour with the exponent beta ~ 1.64. This slope beta does not
depend on the length of the sampled intervals, what suggests some kind
of selfsimilarity in the distribution of primes.
