There are in fact two complementary relationships as between the primes and the natural numbers. From the standard well-known perspective, this relates to the quantitative (base) aspect of such numbers. However from the little regarded alternative perspective it relates to qualitative (dimensional) aspect of such numbers i.e. as represented by factors. So for example, from the former external perspective we might seek to calculate the frequency of primes up to a given natural number. From the latter internal perspective, we might then seek to calculate the ratio of natural to prime factors within this given number. In both contexts, log n is of special importance. In the former external case, it measures the average gap as between prime numbers. In the latter internal case, it measures the average frequency of natural number factors. Thus again in the former case, n/log n measure the average frequency of primes to n. In the latter case n/log n measures the average ga...
